I live in a co-op with 30 other people, 11 cats, and 2 dogs and this summer the fleas have been horrifying! I’ve been trying everything to keep them off of my 5 year old chihuahua and I just can’t seem to keep them off! I’ve been using flea and tick shampoo regularly (once a week) and also apply advantage, but I still pull at least 20 fleas off of him every day! I’ve heard that garlic is a remedy, but it’s also toxic to dogs. Does anyone have any suggestions? Anything helps!
