After returning from a two-week work trip, you notice something unexpected: a small blue tattoo on your dog’s belly. You’re shocked—it wasn’t there before dropping her off at the 24/7 daycare. What does it mean? And more importantly, how could this have happened without your consent?

Pet tattoos, especially small blue or green marks on the abdomen, are commonly used to indicate that an animal has been spayed or neutered. This practice was more widespread before microchipping became common, and some veterinary clinics or grooming facilities may still use it to prevent unnecessary future surgeries. However, such a procedure should never be done without the owner’s knowledge or approval.

Many full-service daycares now offer more than just boarding—they might partner with groomers, trainers, or even in-house veterinary services. If your pet was groomed or examined during her stay, it’s possible the tattoo was added during a routine vet checkup—though this doesn’t excuse the lack of communication.

Here’s what you should do next: review your dog’s medical records for any recent procedures, take clear photos of the tattoo, and immediately contact the daycare to ask specific questions. Was a medical service performed? Do they work with a vet? And why weren’t you informed? Unapproved tattooing is not just unethical—it could have legal consequences. As a pet owner, you have the right to full transparency when it comes to your companion’s care.
