Adopting an adult dog means skipping puppy chaos, but it also means inheriting a health history you may not know. Asking the right questions on day one helps you and your vet plan well.
Questions to ask the shelter or rescue
What is known about the dog's medical history and age?
Which vaccines have been given, including rabies, and when?
Has the dog been spayed or neutered, microchipped and tested for heartworm?
Is the dog on any medication, special diet or parasite prevention?
Any known conditions, past injuries or allergies?
Any history of aggression, anxiety or fear triggers?
Can you share all medical and microchip paperwork?
Get the paperwork
Ask for copies of every record and microchip registration details. Update the chip registration with your name and phone number right away. Then save everything in a digital pet health vault so it's ready for vets, groomers and boarding.
Schedule the first vet visit
Most vets recommend an exam within the first week or two. Expect a full physical, a review of vaccines, parasite testing and a talk about dental health, weight and diet. To book in person, find a nearby veterinarian.
Give your dog time to settle
Many adopters follow a rough 3-3-3 idea: three days to decompress, three weeks to learn the routine, three months to feel at home. Keep the first days calm, with a predictable feeding and walking schedule. Appetite and stool may be off for a few days because of stress.
When to call a vet sooner
Contact a vet if your dog refuses food for more than a day, has ongoing vomiting or diarrhea, coughs, limps or seems very lethargic.
FAQs
Should I change my adopted dog's food right away?
Usually no. Keep the same food at first, then switch gradually with your vet's advice.
