Frequently Asked Questions

How long until I see coat improvement after changing food?

Coat improvement typically shows in 4-8 weeks on appropriate nutrition. Full coat renewal can take 3-4 months since hair grows in cycles. Be patient—nutrition works from the inside out.

Is fish oil necessary if I'm feeding fish-based food?

Fish-based foods provide omega-3s, so additional supplementation may not be necessary. However, dogs with significant coat or skin issues often benefit from additional fish oil. Consult your vet for guidance.

My dog's coat was shiny but has become dull. Why?

Possible causes include: dietary changes, stress, seasonal shedding, underlying health issues, allergies, or aging. If the dullness persists despite good nutrition, consult your vet to rule out health issues.

Can I give my dog human fish oil supplements?

Human fish oil supplements can be used, but dosage differs. Dog-specific products have appropriate concentrations. If using human products, consult your vet for proper dosing based on your dog's size.
