Is Tuna Safe for Border Collies?

Tuna is safe for Border Collies when prepared correctly and offered in appropriate amounts. Canned tuna in water is safe occasionally for dogs — limit mercury for Border Collies. As with any treat, moderation is key — even safe foods can cause digestive upset if given too frequently or in large quantities.

Good protein with omega-3s — mercury risk if overfed daily. Treats should never make up more than 10% of your Border Collie's total daily calorie intake — the remaining 90% should come from a complete, balanced pet food.

⚠️ Preparation note: Always remove Tuna in oil or brine — mercury risk before offering Tuna to your Border Collie. These parts can be harmful even when the rest of the food is safe.
