    1. 2-GI PROBIOTICS 

    Probiotics are mainly used to help your dog's intestinal track when it is upset (i.e., diarrhea), but it can also help with a variety of ailments affecting its skin, eyes or nose. Still, a majority of 2-GI probiotic tablets are given to dogs when they are experiencing an irritated stomach. By giving your dog the appropriate bacteria, probiotics can restore proper balance of intestinal bugs that might be in there. (petMD)

    5. MULTIVITAMIN 

    If you are unsure whether your dog is getting enough of the right nutrients in their everyday food, consider adding a multivitamin to their diet. Nearly a third of U.S. dogs take vitamins on a daily basis. However, if your dog is already on a well-balanced diet, it may not need any additional supplements. Check with your veterinary to see what your dog is lacking before you put him or her on a multivitamin. (petMD)

    12. VITAMIN C 

    Although vitamin C is not required in a dog's diet (since they already process it internally), owners of pets with medical conditions often find that the supplement can help tremendously. Older dogs, canines with symptoms of distemper and hip dysplasia often benefit from vitamin C. It can also help dogs heal broken bones or prevent a urinary tract infection. Vitamin C should be avoided, however, if your pet has a history of urinary oxalate stone formation. This is common in Schnauzers, Lhasa Apsos, Yorkshire Terriers, Miniature Poodles, Shih Tzus and Bichon Frises. Either way, if you are considering supplementing your dog's diet with vitamin C, be sure to consult your veterinarian for the appropriate dose. (petMD)
