Just rescued a Spaniel. Approx 6 months old. The vet examined him and said all's good. We gave him a bath with Mikki Puppy shampoo. Since then he's been scratching himself a lot (for 1 days already) but his skin looks healthy. Any recommendations for a shampoo or perhaps a supplement that will help this itchy condition. Thanks!

That may have been an allergy so it should be gone as long as you stop using the mentioned shampoo.

I use an oatmeal and aloe shampoo. It works wonders! Among supplements if you still need them try fish oil or Omega 3-6-9 in capsules.
