New Rescue Dog Won't Eat? Causes and When to Worry
Why newly adopted dogs often refuse food, gentle ways to help them eat, and when to call your vet.
Stress suppresses appetite, so many new dogs eat little in the first days.
Gentle ways to help
- Put the bowl near the safe spot and walk away. Many scared dogs eat only when no one watches, or at night.
- Toss-feed: sit at a distance and gently toss a few pieces without looking at your dog.
- Keep meals at the same times every day.
- Never force-feed or hover.
When to call your vet
No food for more than 24 hours, any refusal of water, vomiting, diarrhea, lethargy or visible weight loss.
