Where can I learn more?

Fleas, mites, and skin infection copy the look of a food allergy. The elimination diet starts after those are addressed. The trial has a start date and a recheck.

How often should I take my pet to the vet?

Fleas, mites, and skin infection look like a food allergy, so the itch is examined before an elimination diet starts, including in puppies who are already coming in every 3 to 4 weeks until about 16 weeks. Adult dogs need at least one exam a year. Itchy dogs around 7 years old, giant breeds earlier, are often examined about every six months so skin, ears, and weight are checked during the diet trial. The diet trial has a start date and a recheck the clinic sets. Hives, facial swelling, or vomiting right after a meal is a same-day problem.

How can I save money on pet care?

An elimination diet works only if it is the only thing the dog eats, so leftovers, flavored drugs, and a second bag defeat the money you spent on the first diet. Confirm with the clinic that fleas and infection are handled before you start. One diet, one recheck. The cupboard of limited-ingredient experiments is the part you can stop buying.
