# Why won't my rescue dog eat?

> A rescue dog may refuse food because of stress, unfamiliar food, nausea, dental pain, illness, fear of the bowl area or disruption after transport. Short-term pickiness can be normal, but ongoing refusal needs veterinary advice. This answer helps new adopters respond calmly while knowing when appetite loss becomes a medical concern.

## Key takeaways
- Stress commonly affects appetite after adoption.
- Pain, dental disease or illness can also stop eating.
- Give a quiet feeding area and avoid pressure.
- Ongoing refusal needs a vet check.

## Answer
Do not assume a new dog is being stubborn. Stress hormones, noise, pain and anxiety can all suppress appetite.

Offer quiet space, fresh water and familiar food if the rescue provided it. Avoid crowding the dog while they eat.

Call a vet urgently if the dog refuses all food for more than a day, refuses water, vomits, seems weak or is a puppy, senior or medically fragile.

## Why this question matters
A dog arriving from kennels, transport or a foster move may not feel safe enough to eat immediately.

## The welfare-first answer
Food refusal should be treated as information. Make eating low-pressure, keep water available and watch for vomiting, pain, lethargy or dehydration.

## What to do next
Ask the rescue what the dog ate before adoption. If the dog refuses food beyond the early adjustment window or shows illness signs, contact a vet.

## FAQ
### Should I hand-feed my rescue dog?
It can help some dogs, but avoid creating pressure. Offer calmly and let the dog choose.

### Can changing food cause refusal?
Yes. Sudden diet changes can upset digestion or reduce interest.

### When is it urgent?
Refusing water, repeated vomiting, weakness, bloating or appetite loss in puppies and frail dogs is urgent.
