Trying using coconut oil instead of the salmom, I was giving Dolly fish oil my vet said to stop the fish oil and give coconut instead it seem to really help her,
they also had be start using Dermalyte shampoo which is hypo allergenic plus it has coconut oil in it (I really love this) also use Dermapet conditioner which is wonderful. I got this at my vets but you could go on line and order it
