Adopting a dog is a rewarding experience, but it’s essential to be aware of potential red flags that could indicate future challenges. By recognizing these warning signs, you can make informed decisions and ensure a harmonious match for your family.

1. Inability to Meet the Dog Before Adoption
A reputable rescue or shelter will always allow you to meet a dog before finalizing the adoption. If they refuse or make excuses, consider it a significant red flag.
Why this is important:
- Meeting the dog helps assess their temperament and compatibility with your household.
- You can observe how they interact with you and others.
- Ensures there are no unexpected behavioral surprises after adoption.
2. Pressure to Adopt Quickly
Be cautious if a shelter or rescue pressures you to make an immediate decision, suggesting that the dog will be euthanized or adopted by someone else if you don’t act now.
Why this is a red flag:
- A responsible organization gives you time to make an informed choice.
- Rushed adoptions often lead to mismatched placements.
- High-pressure tactics are sometimes used by disreputable rescues to hide issues with the dog.

3. Shady Shelter or Rescue with No Reviews or Vague Information
Before adopting, thoroughly research the organization. A lack of online presence, absence of reviews, or vague information can indicate disreputable operations.
How to protect yourself:
- Look for shelters with verified reviews on Google, Facebook, or adoption sites.
- Visit the facility if possible and ask questions about their process.
- Avoid organizations that evade direct questions or refuse to provide details.
PRO TIP: Search the IRS database OR Candid, GuideStar to ensure the shelter is running a legit non-profit organization.
4. Unclear or Missing Medical History
A trustworthy rescue will provide comprehensive medical records for the dog, including vaccination status, spaying/neutering information, and any known health issues.
What could happen if you ignore this:
- Unexpected medical expenses for untreated conditions.
- Possible exposure to contagious diseases like Parvo or kennel cough.
- Hidden chronic health conditions that require lifelong treatment.
A member of our community adopted a dog and, after bringing her home, noticed signs of illness. A visit to the vet revealed advanced Parvo. Having already fallen in love with the dog, they chose not to return her, but it cost them thousands of dollars to treat the disease.

5. Visible Injuries or Illnesses
Pay attention to the dog’s physical condition. Signs like being underweight, having patches of missing fur, runny eyes or nose, or dirty ears could indicate neglect or underlying health issues.
What to look for:
- Weight loss, visible ribs, or lethargy.
- Open wounds, excessive itching, or hair loss.
- Cloudy eyes or frequent sneezing/coughing.
- Unusual gait or difficulty walking.
A responsible shelter will be upfront about any known conditions and the care the dog has received. If you’re getting vague answers or they’re brushing off your concerns, that’s a red flag.

6. Requests for Unusual Payment Methods
Be wary if an organization insists on unconventional payment methods such as wire transfers, gift cards, or cash only. Reputable shelters typically accept standard payment methods like credit cards or checks. Unusual payment requests can be indicative of scams.

7. “Free Dog” Listings
While it might be tempting to adopt a dog listed as “free,” approach such offers with caution. These dogs may come from individuals looking to rehome their pets quickly, possibly due to behavioral or health issues.
What to consider:
- Some free dogs come with unknown or undisclosed issues.
- Unethical individuals may use free dogs for illegal purposes.
- Ensure the rehoming includes proper vetting and an adoption agreement.

8. Signs of Aggression or Fearfulness
It’s natural for dogs to exhibit some nervousness in new environments, but extreme aggression or fearfulness should be taken seriously. Observe the dog’s behavior closely and ask the shelter about any known behavioral issues.

A few years ago, we adopted a 2-year-old Border Collie to be my daughter’s agility dog. One day after bringing him home, he attacked me. I later found out the dog had a history of a serious bite incident, sending its previous owner to the hospital before being surrendered to the rescue.
This was a terrifying and dangerous situation that could have been avoided if the rescue had been transparent about his past behavior. You can read more about our story here.
Trust Your Instincts
Throughout the adoption process, trust your instincts. If something doesn’t feel right—be it the organization’s practices or the dog’s behavior—it’s okay to step back. There are many dogs in need of loving homes, and it’s crucial to find the right fit for both you and the dog.
Consider a Foster-to-Adopt Program
One of the best ways to ensure a great match is by participating in a foster-to-adopt program. Many reputable rescues offer this option, allowing you to bring a dog into your home temporarily before making a final commitment.
📖 PRO TIP: Learn How to Foster a Dog
Benefits of fostering to adopt:
- Gives both you and the dog time to adjust.
- Helps assess how the dog fits into your lifestyle.
- Provides insight into any behavioral or medical needs.

For a comprehensive guide to navigating the adoption process, consider utilizing resources like the Dog Adoption Workbook, which offers checklists and questions to ensure a successful adoption experience.
By staying informed and vigilant, you can make the adoption process a positive and fulfilling experience for both you and your new canine companion.
Yes, I spent years trying to adopt from local rescues but as I needed a small dog due to my age and fitness, it was quite difficult as they seemed to have many applications. A percentage stipulated you needed another dog , or no pets, no cats, etc. And some didn't consider older people like ourselves. I ended up adopting from overseas as a last resort, but the dog was nothing like their bio in reality and has severe leash aggression and will attack other dogs unprovoked and doesn't like cats or car rides unlike the description of being good with all of these. In retrospect, I would have preferred to have a trial period or had a dog that had been fostered in a home first as then they might have been able to assess more thoroughly and state the behavioural issues.
I am so sorry you had such a bad experience. It’s unfortunate that good people like yourself have to go to extremes to adopt a dog and then end up with a dog that isn’t a good match. I hope things work out for you.
