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.

Hi Debi, I have adopted a 3 yo rescue dog for 5 months now. He was fine in the first 2 months but started showing fearful behavioural issues after that. We were not informed of his anxieties prior to that. We decided to work on it anyway and engaged a behaviourist for 4 months now. He is also on meds for his anxieties. But the thunder phobia is severe and it doesn’t help that we have to be out for work and he has recently developed separation anxiety. Not sure what else to do.
Hi Sam, there are a bunch of articles about fear, separation anxiety, etc here on the blog. Read these and hopefully things will get better:

Hi,
I’ve adopted a beautiful boy, podenco x greyhound. He loves my other two dogs and is very playful. We’ve only had him 5 days, and he seems to be suffering with separation anxiety, especially where I am concerned. I am trying to extend the amount of time I leave him with my other two, who seem very relaxed around him, even when barking when I leave the room. He is especially bad at night, we have a routine with our other two dogs (3 yrs female and 11 yrs female). He barks within 5 mins of leaving him at night, so I come down, try to settle then leave him again. I do allow home to bark or whine for about 10 mins before re-entering the room.
I have had to then sleep downstairs after about the third occasion, as we are attached to our neighbours.
My husband thinks he should be settled immediately and gets frustrated at me for Arlo now settling into a night routine, sleeping with his two fur sisters. I have tried to tell him it can take a good couple of weeks to become settled. Please help me. He came from a home with three children under 11yrs. But did like a crate.
Many thanks
We adopted a rescue 5 weeks ago. He does ok, but is very quite anxious especially in the evenings. Pacing and panting, can’t settle down. He has also nipped my husband and brother in law. I believe was situational too close to his food bowl and drying wet paws. Also, hand feeding him and petting at the same time it happened again. He also snarled at my 11 year old neice unprovoked. What do we do? We are getting to the point we almost want to return him. It is very stressful.
I feel your frustration. I recommend reaching out to a professional behaviorist dog trainer. They could help assess the situation and give you a training plan to help his anxiety. There are a couple articles you should read: Our Heartbreaking, Gut Wrenching Adoption Story. And then read Is it Ever Okay to Rehome a Dog?. In the end you need to make the right decision based on what you are comfortable with and what is best for your family.
Hi! I just adopted what we believe to be a 2yr boxer. It’s day 3 and he’s actually been really good. He’s house broken and does pretty well in the crate, only whines a bit before settling down. He likes being around both me and my bf. The shelter told us he’s good with people, kids and dogs and his foster vouched for this after having him 2 weeks. He mainly needs work on basic manners. He doesn’t seem to know any common commands and could get a little jumpy when he’s excited to see us.We haven’t ventured out with him and we have a backyard so I was going to wait a week until we start taking him on walks. I have two questions:
1) Is it possible this is too good to be true?
2)How soon is too soon to take him out to public places where there may be dogs and people? Or is it a good time to start testing his behavior in public? At this point he’s only interacted with my and my BF in our home. (Other than his experience with his foster)

hi debi, just a short note, as you know i adopted my Loki about 3 weeks ago. he has settled in so nicely and so has mom and dad. he does have separation anxiety realy bad, so we are working on that. we are signing him up for training in a few weeks, which we be beneficial to him and us. he got away from us a few days ago and we had a realy hard time catching him. he didnt hear any of my callings, he just wanted to run. he ran for an hour before we could get him. that wont happen again,hopefully
This is very helpful and I wish I had found it sooner. We’ve had our new family member just over a week. Given my words on introducing her to her home and our other dog she has adjusted amazingly well. She is not good aggressive but I just found out that it’s recommended to place their food in separate rooms until they are very secure in their own food bowls and schedule. We have scheduled morning and evening feed times and it has made it easier on her system to adjust to bathroom breaks as well. The first few days we found poop in the house but not the last 6 days. She was confused on which feeding spot was hers and today we were advised to use different rooms. I feel strongly that she will adjust well. My only question would be when introducing a rescue dog to another rescue that is used to being the only dog….. how can you let both know they’re loved without the first dog feeling replaced?
I just rescued an Australian shepherd/pointer mix, about 16 months old. He lived with 3 other dogs in his foster home, and was deemed dog-friendly. He is my only dog in the house. When we go on walks he wags his tail at other dogs and wants to go meet them, after a few seconds of sniffing, a switch happens and he starts growling at them. I had a friend bring over her puppy, and he would get aggressive when he sniffed the puppy, the puppy was interested in his toys or when I held the other puppy. What is causing him to be aggressive and is this normal to happen during a transition phase? What can I do to help make him more comfortable? We are on day 4.
3 days is very early. He is unsure and scared I would keep other dog interactions limited at this point. Wait until he has more time to settle and learn to trust you.
We’ve had our rescue husky, Luna, for about 2 weeks now. I feel she’s definitely acclimated with my husband and I and our 6 month old. She is slowly letting us in and she does well with our other dog, buttercup who even went into her crate and luna was fine. However, luna still does a little growl and a bark at my mother in law but only really when she tries to call her over. I don’t know if it’s because she doesn’t see her all day, we stay at home all day with her, or if she’s just not comfortable yet. But I just want to know how to fix it, give her more time or it’s a behavior I need to worry about
It sounds to me that it’s out of fear not agression. Try and have your MIL feed Luna treats, maybe sit on the floor and allow Luna to approach her without forcing it. 2 weeks is still very new. Give her time and she will learn to trust more and more every day.
Hello. I adopted a dog from a rescue. She came from a hoarding situation, and that is all I know about her past. She is extremely fearful of everything, and only wants to stay in her bed. I cannot get her to get up out of the bed on her own, and I have tried everything. I have tried waiting for her to have to go to the bathroom bad enough,, but I was concerned that she might create a health problem by holding it in for too long. She is a Golden Retriever mix, and she is so heavy. It is difficult for me to try to make her get up to go outside to potty. She did go out on her own a few times without a leash, but that ended up with her hiding in the corner of my backyard behind some rose bushes. I have Parkinson’s, and I was not able to get her out. My sister had to come over and do it. This morning I thought I would try seeing if she would get out of her bed and come with me into the living room (where she has been staying for the past week). She heard me pouring her food, and it looked very promising…. she stood up in her bed and started wagging her tail! She even got out of her bed when I said “let’s go Maggie.” She was still wagging her tail. But when she got to the doorway, she retreated back to her bed, and she hasn’t gotten back up again. Advice would be greatly appreciated!
You didn’t mention how long you’ve had her. I really sounds like she just needs time to trust you. I know it’s hard, but try and think about it from her perspective.
Hello! My husband and I rescued a dog almost three weeks ago and we have been having issues with her escaping our fenced in yard. We have reenforced our fence in every way imaginable and have tethered her as well. We are keeping a close eye on her any time she is in the yard now, even though she is tethered and are worried about her teaching our other dog how to escape. We are wondering if this is something that is typical of rescue dogs and hopefully will go away once she becomes more settled?
She may be scared, is she showing any other signs of stress? Or maybe bored? Is she getting enough physical and mental exercise?
