Quick Answers

Where can I learn more?

Animals in one house do not share one chart. The Companion Animal Parasite Council guidelines are the reading before a new dog mixes with the dogs already there, and the AAFP feline retrovirus guidelines are the reading before a new cat mixes with the cats. Diarrhea that moves from one animal to the next is an exam for the animals involved.

How often should I take my pet to the vet?

Animals who share a house do not share one exam date. Each puppy or kitten is seen every 3 to 4 weeks until about 16 weeks. Each adult dog or cat needs about one exam a year. Senior dogs, often from about 7 years and earlier in giant breeds, and senior cats from about 10, are commonly seen every six months on their own charts. A newcomer should be examined before full mixing so parasites and vaccine gaps are known. Diarrhea that jumps from one animal to another, or a bite wound, is a visit for the animals involved.

How can I save money on pet care?

Do not split one animal's preventive, prescription diet, or medication across the others to save a box. Doses are not interchangeable, and some dog products are toxic to cats. Each animal needs the product labeled for that species and that weight, and each needs their own exam. Save by skipping second copies of anything the shelter or clinic already dispensed, and by buying family-size items only when every pet uses them.

Give a new pet a closed door and swapped bedding before any face-to-face meeting. Feed both animals on their own side of that door. A fight in the first hour is remembered for a long time. Duplicate the resources: litter boxes or crates, water bowls, and resting spots, so one animal cannot blockade the only one. Separate them again at the first hard stare that does not relax.
