I think I need to start adding in some fish oil. Rocky is scratching quite a bit and his coat is dry this summer. We have 100 degree heat constantly and he is in air conditioning non-stop which doesn't help. My new little guy is on "Icelandic Pure" anchovy and sardine oil which the breeder recommends but is VERY expensive for 3 dogs, two of which are 90 pounds! I will get it if it is that really that good for them and will help Rocky's fur. Are there any other brands and varieties that you recommend? I know that he can't have flax oils, he will itch even more. Anything else he seems to be okay with.
