My 12 kg West Highland White Terrier ate three of those raw-egg-white-chew treats from the pet store yesterday. Are they safe?

Short answer

No — raw egg white contains avidin, which locks up biotin in the gut and blocks its absorption. A single incident like three treats is unlikely to cause immediate damage, but repeated exposure can lead to dermatitis, a brittle dry coat, hair loss, and lethargy. Check the ingredient list on any supplement or treat: if raw egg white or raw egg appears, remove it from your dog's rotation. Watch for flaky skin or unusual tiredness over the next few weeks. Call your vet or the ASPCA poison line at 888-426-4435 if your dog shows any of those signs.

Why three treats worry more for a 12 kg dog

Westies are small enough that multiple raw egg white exposures stack up faster than in larger breeds. While one treat might pass through with minimal biotin blockage, three in a day means more avidin binding to his gut nutrients. Watch closely for the next 48 hours: excessive face-rubbing or foot-licking can signal early skin irritation from the deficiency.

Check his usual treats — some 'healthy' brands use raw egg whites as binder. Switch to single-protein treats like dehydrated liver or salmon until his system resets. If he's on a fish-based diet already, the natural biotin there helps counterbalance some loss.

The hidden risk in commercial pet products

Many owners assume pet store items are vetted for safety, but supplements and chews aren't held to the same standards as kibble. Always scan for 'dried egg white' or 'albumin' in ingredients — these are raw unless specified as cooked. Even 'natural' labels don't guarantee heat treatment.

Contact the treat manufacturer to ask about their egg processing. If they can't confirm pasteurization or cooking above 70°C (158°F), discontinue use. Safer alternatives exist: look for treats with egg further down the list (indicating smaller amounts) or those explicitly labeled 'cooked egg whites'.

Westie-specific symptoms to monitor

This breed's white coat makes skin issues easier to spot. Part his fur weekly to check for pinkish skin or tiny scabs, especially along the back and tail base. Westies already prone to dry skin will show deficiency signs sooner — increased scratching or dandruff means call your vet.

Their energetic nature helps detect lethargy: if he's napping more than usual or seems less interested in play after 3-5 days, it's worth a checkup. Keep his regular grooming schedule — brushing helps you notice hair loss early, particularly around the ears and elbows.

Balancing treats without raw eggs

For dogs who love chewy textures, try freeze-dried chicken hearts or sweet potato slices. If you used these treats for training, substitute small bits of cooked chicken breast or commercial treats with baked egg components.

When introducing new treats, offer one piece and wait 24 hours to check for allergies. Cook a batch of plain scrambled eggs (no oil or salt), chop them into pea-sized bits, freeze on a tray, then store in a bag for occasional rewards — this gives safe egg flavor without risk.
