Ok not sure how to explain it but I have a 5 month old black German Sheppard he has never had fleas but he is always itchy not to the extreme but he does itch . He is always chasing his tail I think that may jus be puppy play.I kno he has worms I've been given him medicine for it but they jus don't seem to go away . Also another real concern of mine is he is having slight hair loss around his eyes no were else . The spot on his head is a sore the hair is coming back. I'm limited on things to do

Submit a stool sample to your veterinarian to diagnose the exact intestinal parasites Juju may have. The appropriate dewormer can be dispensed afterwards and repeated in 2 weeks. You'll need to submit another stool sample to confirm resolution. Keep him away from areas with feces and pick up his stool immediately to prevent reinvention. A monthly preventative, such as HeartGard, will protect against heartworm disease as well as the 3 most common intestinal parasites of dogs (hookworm, roundworm and whipworm). For the itch, use a monthly flea preventative, such as Frontline, K9 Advantix or Revolution, for at least three consecutive months. Do this even if you don't see any fleas. In a sensitive dog, just one flea bite may cause severe itching. Vacuum everywhere and wash all bedding. Use an area treatment, such as Knockout ES or Indorex, to treat fleas that may be living in the environment. You may need to have your veterinarian perform skin scrapes to check for mites which can cause itching and hairless. Discuss allergy testing, hydrolyzed diets, antihistamine use and food elimination trials with your veterinarian in case there is an allergic component to the itching.
