We use it as a kibble topper - just a couple of tablespoons and a little water. We usually get the lamb and rice and chicken and rice variety. We've never had any issues with it.
Elliott, who is about 85 lbs, wears a size TE on his front left paw. I put a toddler sock on his paw first, and then the boot. It gives extra padding, keeps the boot cleaner and looks cute.
I didn't think I was squeamish, but that last pic was ick. I know they use leaches and even maggots to treat certain conditions - I wonder how the leaching helps relieve arthritis?
I vote impacted anal glands. About a year ago I posted that Elliott was constantly licking his bum despite having recently had his glands expressed. At the advice of other greytalkers we took him back for a recheck and he had an infection in his anal glands which could have become serious if we hadn't brought him in when we did.
