Question:  I am concerned that I am overdoing the quantity and/or type of supplements I give my dog Charlie.  She has Allergy tablets, Digest Soft Chews, Joint Plus tablets, Breath Fresh tabs and Omega Oil. In addition to those Uckele products she has Liver Support by Vetclassics which ostensibly supports Normal Liver Function. This last one is sold to me by Charlie's vet. It contains amongst other things Glutathione, Milk Thistle, B-Vitamins, Dandelion Root. Charlie also takes 1 capsule of Gabapentin 100mg, prescribed by vet plus I give her a hemp supplement. Charlie is a Staffordshire Bull Terrier, 15 years old. She had surgery when she was 8 for a ruptured disc and recovered well but as she ages her hind end has become stiffer, but she is still able to walk. Her appetite is good although it seems it is difficult to put weight on. However since I stopped prednisolone (vet prescribed but I don't agree!) a few months ago her digestion and her stools are much better which I attribute to the hemp supplement and your digestive supplement. She developed ringworm a few months ago and she has been having sulphur baths once a week to try and get rid of it. It was only when I asked the vet to do a skin scrape that the ringworm was diagnosed as Charlie had been having skin problems,which was annoying. I also caught the fungus on my wrist which was doubly annoying! Sorry this question is so long winded but there are a lot of seemingly connected things and I find it difficult to analyse supplements when there are so many ingredients in varying proportions. Dr. Kellon: There's no problem with combining the ingredients in these various supplements. With any supplement you have to ask whether she needs it and does it actually help.  An even bigger question is why does she need it.  When a dog has a wide constellation of problems like this, I look to the basic diet. The plant/vegetable type ingredients, fiber sources can cause issues for some dogs and it might be worth experimenting with fresh, preferably raw, primarily meat based diets.
