Short answer

Raw freshwater trout can carry parasites, and signs usually appear within 6 to 48 hours after ingestion. Watch for vomiting, diarrhea, loss of appetite, or unusual tiredness. Most parasite-related illness shows up within the first two days. If your dog starts vomiting repeatedly, seems dehydrated, or becomes very lethargic, call your vet right away. In the meantime, offer small amounts of water frequently and do not force-feed. Cooking fish thoroughly eliminates this risk for next time.

Trout — Food safety facts

Safe to share · Dogs · full breakdown on the linked food page

Cooked trout is safe. Raw freshwater fish carries parasite risk.

Dogs and cats carry the same rating (Safe to share), so the notes below hold for either pet.

Trout is not toxic to dogs. The real limit is calories, fat and salt, so treat it as a small extra alongside the normal ration rather than a meal in itself.

There is no poisoning risk here, and the usual problem is simply eating too much at once: a heavy fat or salt load can bring on loose stools or a single vomit. Offer water, keep an eye on the pet for 24 hours, and do not induce vomiting.

Why these cautions matter

Raw animal protein carries Salmonella and E. coli risk, and those bacteria can spread to the people in the household too.
