My 7 year old lab/shepard mix belly started turning black when he was 6. I started giving him my 1200 mgs of fish oil with Omega 3 and it took a couple months but he now has his pink belly back. His skin does not flake when I scratch his back for him either. It was hard to get him to swallow the capsule so I poked a hole in it and squeesed it into his mouth then he decided he liked it and eats it all. If it is goof for my heart it should be good for his too. I started out with 2 tabs a day but now that he is back to his nice pink belly I give him one a day .View Thread
I don't know what causes it but it happen to my 6 year old and then I started giving him 1200 mg of fish oil with Omega-3 twice a day and it cleared up completely. I had a hard time getting him to swallow the gel capsule so I poked a hole in the end of it and squeesed it into his mouth and then he will eat the hole thing.View Thread
