A confident read of this side of pet care puts you in a better position to make decisions the animal can actually feel. Some iteration is normal, a pet tends to signal clearly when something fits and when it does not.
Where can I learn more?
The American Veterinary Society of Animal Behavior describes introductions as parallel walks and separate resources before the dogs share a toy. A puppy should finish the core vaccines before dog parks. An older dog that growls over a bone needs management, and a painful older dog needs an exam before you call it jealousy.
How often should I take my pet to the vet?
The puppy and the adult dog keep separate calendars during an introduction. The puppy is examined every 3 to 4 weeks until about 16 weeks for vaccines and parasite control, and should not meet random dogs at a park during that stretch. The adult still needs at least a yearly exam, and a visit about every six months if that dog is near 7 years or is a giant breed. A fight wound, a limp after a scuffle, or diarrhea in the puppy is a visit now. Grumpiness in the older dog is often pain, which is an exam finding.
How can I save money on pet care?
A fight wound is an urgent care fee, and a puppy who gets sick after meeting random dogs during the vaccine series can be a parvovirus bill. The slower introduction, and keeping the puppy's visits every 3 to 4 weeks until about 16 weeks, is the spending that avoids both. You do not need a cart of new beds and bowls for the first day. You need a door both dogs can be separated behind.
