Working With Your Veterinarian
- Options may include flavored preparations, transdermal gels, or custom-dosed capsules when the veterinarian determines they are appropriate.
- Tell your veterinarian about anything your pet cannot tolerate — sensitivities matter for the formulation.
- Request refills before your pet’s supply runs low, and ask us how much lead time the prescription needs.
- For pickup, wait for the pharmacy to confirm the preparation is ready before traveling to Rancho Cucamonga.
