What is the 3-3-3 Rule for Dogs?
The 3-3-3 rule is a general guideline that represents the phases of a rescue dog or common milestones your new dog will go through… it is the first 3 days, 3 weeks, and 3 months after bringing your dog home from the shelter.
The 3-3-3 rule is sometimes referred to as the “rescue dog honeymoon period.”
If you’ve ever started a new job or moved to a new school, you know the feeling of being in an unfamiliar place, new surroundings, new people, and new rules. This is how your dog feels as they adjust to their new home.
The 3 Stages of the 3-3-3 Rule
Please note that this is a guideline. The time your dog needs to adjust is as unique as they are.
Here’s what those first 3 days, 3 weeks, and 3 months look like in real life…
3 Days: Decompression
Your dog is likely overwhelmed, nervous, and unsure. Don’t expect too much right away. They might not eat or drink much and could be scared or unsure about their new environment.
Due to the stress, potty accidents may occur. During this time, they might hide or be very cautious around you and your family. Alternatively, they might test boundaries to see what they can get away with, similar to a teenager.
- Feeling overwhelmed
- Maybe scared and unsure of what is going on
- Not comfortable enough to be “themself”
- May not want to eat or drink
- Shut down and wants to curl up in his crate or hide under a table
- Testing the boundaries
3 Weeks: Learning the Routine
By now, your dog will typically start to settle in, feeling a little more comfortable and beginning to understand their new routine. They may start to show their true personality and begin to trust you more.
- Starting to settle in
- Feeling more comfortable
- Realizing this could possibly be their forever home
- Figured out their environment
- Getting into a routine
- Let their guard down and may start showing their true personality
- Behavior issues may start showing up
3 Months: Feeling at Home
This is when transformation shines. Your dog may start to trust you and feel secure in their new home. They may begin to settle into a routine and become comfortable with their environment.
This period is when you will see your dog’s true personality and begin to build a deeper bond.
- Finally, completely comfortable in his home.
- Building trust and a true bond
- Gained a complete sense of security with his new family
- Set in a routine
Adjusting to the Timeline
Remember, these timelines are general guidelines. Every dog is unique, and some may take longer to adjust. It’s important to be patient and not rush the process.
If your dog takes 6, 8, or even 12 months to fully adjust, that’s completely normal. The key is to provide a consistent, loving environment and celebrate the small victories along the way.
Your understanding and support during these phases are crucial in helping your rescue dog feel at home and begin to thrive.
Enjoy your newly adopted dog, give them love, support, and time, and they will soon become your best friend!
Common Mistakes Adopters Make
- Expecting their dog to be “normal” instantly.
- Flooding them with too many new people, places, or dogs.
- Initially, letting rules slide, then trying to enforce them later.
- Ignoring subtle stress signals (panting, pacing, avoidance).
Tips for Success
- Stick to the 3-3-3 timeline as a guideline, not a rigid rule. Every dog adjusts at their own pace.
- Focus on structure and bonding over tricks or obedience in the first weeks.
- Use enrichment games and confidence-building activities to help anxious dogs.
- Be patient. Progress isn’t always linear, but the payoff is huge.

The Origin of the 3-3-3 Rule
The 3-3-3 Rule was originally created over 15 years ago by Sue Kroyer, a long-time rescuer who ran the Cocker Connection Rescue in Los Angeles. She shared it with discouraged adopters to give them a perspective on what to expect.
Years later, I (Debi McKee, Rescue Dogs 101) designed the now well-known 3-3-3 graphic and wrote one of the first comprehensive blog posts explaining the rule in detail. That visual made the 3-3-3 Rule easy to share… and it quickly spread across the internet.
So while Sue is the originator of the concept, I’m grateful to have helped bring it to life visually and make it accessible to adopters and rescues worldwide.
FAQs About the 3-3-3 Rule
How long will it take MY rescue dog to adjust?
The honest answer is, it depends. Some dogs will follow the 3-3-3 rule to the letter, while others may take 6 months or a full year to feel completely comfortable.
Keep in mind that the 3-3-3 dog rule is a general guideline. It will depend on the situation the dog was surrendered, the dog’s personality, and their background.
What can I do to help my rescue dog adjust faster?
Patience is key, but there are ways to support your dog. Keep routines predictable, offer a safe space, use calm and positive reinforcement, and avoid overwhelming them with too many new experiences at once. Small, consistent steps build trust faster than rushing things.
Should I follow the 3-3-3 Rule exactly?
The 3-3-3 Rule is a guideline, not a strict formula. Every dog is different. Some may breeze through in a matter of weeks, while others may need many months. Use the rule as a framework to set expectations, but always follow your dog’s pace.
What if my dog isn’t improving after 3 months?
Don’t panic… many rescue dogs take 6 months to a year to feel fully settled. If your dog still appears anxious, consider consulting a trainer or veterinarian to rule out any underlying medical issues. Progress may be slower, but with consistency and patience, most dogs come around.
Final Thoughts
I encourage you to take it slow. I know it’s exciting to get a new dog, but see life through your dog’s eyes…
They have been through a lot, they may have lost their family, possibly been abused, or abandoned in a noisy shelter, … it’s all very stressful. Your dog needs time, so give it to them.
Remember, the 3-3-3 dog rule is a general guideline. Your dog will go at their own pace during this “honeymoon period”; it could take 4, 5, or maybe even 6 months.
Each dog is unique. Just be there for them, comfort them when they need it, and create a positive, safe environment, and you will be on your way to raising your perfect dog.

Good advice! We adopted a beagle mix three weeks ago today. She's a totally different dog, in a good way, than she was then. Today she initiated play, progress! She's a beagle, stubborn and headstrong but a sweetheart, too. She finally seems happy here. We're working on our outdoor manners. Every walk is an adventure! We adopted her from our local humane society but she came here from another state. We don't know much of her past but she has a few scars that make me think she had a tough life. They said she was 5 but her vet said she's younger, 2-3, with beautiful teeth. Still time to learn!! ( Both of us!)
Hi Debi, great site. I just got a 2 year old rescue poodle that had a troubled past 2 days ago. She was abandoned, abused by former owners, and traveled in crates to multiple locations until we found her. The foster mom noted that she likes females, but gets defensive to males. I noticed that too on our first meet and greet. When we brought her into our home, she was very warm and social to us both plus our existing dog, but I noticed she would randomly get into defense mode and start barking at me. Just walking into the room, its like she forgot who I was. Today, she started barking at me again, but actually reached over and bit onto my shorts. Not good. Based on your 3-3-3 rule, I think she is still adjusting, but I hope that this random barking and attacking to males is not some of her true colors and defense behaviors learned from her previous owners. Any advice on how to positively reinforce trust? Not giving up on her.
Right now just give her time and space. Allowing her to come to you. There are a two articles that could help guide you in the right direction:
Adopting a fearful dog and how to help, and How to Bond with Your Dog (and Why It Matters)
I don’t know if I just got lucky with this dog or if it was fate for us to meet. We lost our son almost 7 weeks ago, so I wanted/needed a buddy for myself when my s/o is at work. Sancho has been great so far. He was surrendered from the previous owner who says she got him from a rescue in the area. We got him Saturday and it seems like he adjusted well right away almost. He doesn’t bark or growl, only the first 10 minutes of meeting, but now he stays by my side. So far from your list, I’m surprised I’m doing everything right. The only thing I worry about now is his stool. The first time was great color and consistency. But yesterday and this morning, it’s been more diarrhea like. I feed him a half cup 3x a day and he had plenty of water available. He does eat grass which I try to stop him from doing. Should I be worried? I do want to take him for a checkup anyway just for reassurance for myself that he has his shots and is chipped.
So sorry for your loss of your son. And congrats on your new puppy. You’ve had him for 2 days, so it’s all very new for both of you. Continue to give him the time and space he needs. New behaviors (not necessarily good or bad) will start to emerge as he becomes more and more comfortable. I wouldn’t be too concerned about the loose stool unless he is not eating or is lethargic. Of course, I am NOT a vet, so consult yours if you are concerned. If you changed foods from what he was eating before he came to you, that could cause some issues. If it doesn’t get better soon, then for sure get him into your vet.
Hi Debi, we rescued an roughly 6 y/o Aussie mix last September, Lulu. I am just now finding this article and we didn't follow any of these rules when introducing her to our home with our 16 y/o mutt Molly whose sister had just passed a week earlier. But nevertheless she has adapted and doing fine. However, we brought home a new puppy in April (blue heeler) for her to play with when she gets bigger; now new puppy is 5 months old and 30 pounds and they play some. Lulu nor Gracie have known me to leave the house for very long, as I work from home and do school online since 2020. The problem I'm having is lately when I leave the house for a couple of hours at a time, Lulu is peeing in the floor again. She is potty trained and is let out right before I leave. Gracie is fine b/c I leave her in the crate and close the door while I'm gone. I am starting to return to work some and will be gone 3 days a week starting August. Any suggestions on things I can do to help prevent Lulu from having accidents? I don't think anything is medically wrong with her, I truly believe she has anxiety when I leave. I know every situation is unique, just wondering if you had any thoughts on the matter. Thanks.
Potty accidents could be anxiety or even behavior related. It couldn’t hurt to get her checked out by your vet to confirm she doesn’t have a UTI. A few articles to read:
Hi, I got a rescue dog 2.5 weeks ago. He is very loving inside the home with me and my partner and he lets us pet him and touch him anywhere. Outside he is a disaster. He is scared of people and dogs, and anything that is loud or has quick movements. He is 11 months old and all we know is that he is a stray. He has growled and barked at people sometimes, especially if they are near me. I think he is being overly protective of me and this is concerning, especially since there are many kids in our close family. I feel like I don't have confidence that he may not bite someone. When he is outside he doesn't take treats, probably because he is so anxious and scared. I have also tried slowly introducing him to a family member but he is still on very high alert and can still growl. The dog is a pointer mix and seems to have a very protective nature. I am worried we won't be able to to have any people over or go anywhere with him to others houses. Please let me know if you think this is something that can be changed or may take a long time. He may not fit with our lifestyle.
Yes it can be changed. Yes it can take a long time. Every dog is different so I can’t give you an exact timeline. But I can tell you it will take time and training and patience.
Hi. I have been reading about your rescue dog. I just wanted to let you know I have a dog similar to yours but she is a German Shepherd X . I have had her 18 months now rescue at the age of 18 months. Scared of everything. People noises and a nightmare when walking. But now she is so much more confident. Like you I still feel a little worried when people approach her and I tell them she needs space and she needs to come to you not you approach her and it works. I give them a biscuit to give her and if she takes it they are ok. No one knows what our poor dogs have been through and its only us that can let our dogs know they are safe. Like you I lack confidence at times but our dogs sense this so it's up to us to show them not to be afraid. Hard work I know. I do hope things are working out for you now as I see your post was in July 2021
Hi Debi,
I adopted a dog five days ago, she's three and was a rescued stray. So far she is actually very well-behaved in terms of general commands, not chewing things she shouldn't and walking on a leash, but she is incredibly afraid of my stairs. She will go up, but not down. I added treads so she wouldn't slip on them, but she's still afraid. How do I remedy this?
Also, I can't get her to poop outside. She pees sometimes outside, but never poops, and only poops inside when I'm not around for a bit either because of work or just showering.
Congrats on your new adoption! For the stairs, have you tried putting treats on each tread? Use a treat she can’t resist. Another option would be to find a friend with a dog that does well with stairs to show your dog that it’s okay. Dogs learn quickest by watching other dogs behaviors. For the pooping outside, you will need to limit her freedom inside until she gets the idea of potty outside only. Use a playpen or a crate. She obviously still isn’t comfortable enough to poop in front of you, so be patient and try taking longer walks outside. Go back to the basics of potty training.

Hi Debi, I've adopted a stray dog 5 days back. She used to live in front of our house and had a couple of friends there. I brought her home because she has always been friendly and affectionate towards me and my family. Before, she used to spend the day at our house and leave at night.
But ever since I brought her home she has been very restless, especially at night. She also has to be forced to be brought back in after walks. It has been only 5 days but my family members are already frustrated because of her whining and crying at night, they also tend to feel bad for her and says that I'm holding her captive.
Will this ever resolve? will she adjust to our home? How long it could take her to settle with us and bond with me, if she ever does?
5 days is such a short time. She has lived on the streets for her entire life. Can it get better? Yes. But it will take months, maybe even years… it all depends on the dog.
I've rehomed a jack Russell she is about 4yrs old. From what I've found out the old owner fed her only on cat food so I'm finding it tough to get her to eat. I've now had her 3 weeks and worried she's nit eating enough, I've given her chicken and she eats that fine. Any ideas would be great, thank you x
You can mix in chicken broth, wet dog food, warm water, freeze dried meal toppers, olive oil, eggs, sweet potatoes, tuna, salmon oil, etc.
Or you could even try using his food as a form of treats throughout the day rather than set feeding times.
My 8 month old German Shepherd is very sweet and playful with me but not with others. How can I fix this?
Not others? People or dogs? GSD’s are known to be loyal to one person so it doesn’t surprise me he doesn’t want to play with other people. And if he doesn’t want to play with other dogs, there could be many reasons, lack of confidence or simply his personality.
Hi Debi,
Just curious. Would you consider the 3-3-3 rule strictly?
Wouldn't there be some dogs that take far longer to come out of their shell and show their personalities etc?
And if that's the case, would you rather just go with the gut feeling instead?
But thank you for your content, it certainly is informative!
I had a rescue Chihuahua (has passed on, sadly) who took several months to trust us before becoming the best dog I could ever have. This article reminded me of him and the good times we had.
All dogs are unique and yes of course the 3-3-3 rule is fluid and I state several times that this is a GENERAL rule only. Some dogs take less time while others could take a year. Every situation and dog is different.
