When to Contact a Veterinarian

Seek urgent veterinary care for trouble breathing, collapse, repeated vomiting or diarrhea, severe pain, bloating, inability to urinate or defecate, seizures, suspected toxin exposure, or sudden major behavior or mobility changes.
Avoid unsupported shortcuts: cure joint pain, guaranteed relief, safe for every dog, replace medications with omega-3, no need for vet.
