Key Buying Factors
Limited ingredients
Fewer ingredients reduce the chance of triggering allergies. Look for single protein source and minimal additives.
Omega-3 fatty acids
Fish oil, flaxseed, or algal oil help reduce skin inflammation and improve coat condition.
Probiotics
Beneficial bacteria support gut health, which is closely linked to immune response and skin health.
Novel protein source
Venison, duck, or salmon are less likely to cause reactions than common proteins like chicken or beef.
No artificial additives
Avoid treats with artificial colors, flavors, or preservatives that can exacerbate sensitivities.
Size and texture
Large dogs need appropriately sized treats to prevent choking, with a texture that promotes dental health.
Care, Cost and Maintenance
Introduce new treats gradually
Start with a small amount and monitor for any signs of digestive upset or itching over 3-5 days.
Rotate proteins
If using limited ingredient treats, consider rotating between 2-3 novel proteins to reduce the risk of developing new sensitivities.
Store properly
Keep treats in a cool, dry place and seal the bag after each use to maintain freshness and prevent spoilage.
Our team recommends pairing a high-quality limited ingredient treat with a fish oil supplement for double the skin-soothing benefits. Always check treat ingredients against your dog's specific allergies, what works for one dog may not work for another.
