The fish oil is can be "tricky??" It's "Fat Soluble" so it can build up in the fat layers of the skin.I hope his hair is doing better. It's hard to believe the poodle is already 2!
Have you tried fish or omega oil vitamins? I forget which it was our vet tech said helps with their fur, but I'm sure you can find it online. That may help from the inside....
Best to go to a "Vet" first to get it?? And Human Grade Fish Oil and Pet Grade Fish Oil are not identical?? Pet Fish Oil has Vitamin E in it and Human Grade does not.
And my understanding is you can use Human grade Fish Oil, but you need to supplement it with Vitamin E??? Another fat soluble vitamin???
Dog's need Vitamin E in Fish Oil cuz other wise ... they can't assimilate it?? I only know because, Rocky used Fish Oil from the Vet. So I had both bottles.
But really Coconut oil is easier (non refined) as you can put it on and/or feed it to them.
I only know this stuff cuz of Rocky WL GSD and for a number of years he was a "itchy nightmare???" We finally got that under control, with a Grain Free Diet ... which in retrospect?? I think may have led to heart failure, lack of Taurine?? But I don't know.
But "grain free food" is another topic.
