Thanks for all the advice, I've been using itch relief shampoo and conditioner as you all recommended, and also (I know a few people are skeptical about this, and this happened before I joined this forum...) I've been feeding Stewie Hill's A/Z diet, my vet told me to feed him this diligently for at least 2 months to eliminate all other substances from his diet, in order to find out what has been making him itch so badly in the past. His scratching has improved drastically, I must say. Even though he still rubs himself against "stuff", it's not as frequent and he doesn't scratch himself as "violently" as he used to. However, there's something else that I just realized might be a problem here, Stewie eats poop, not so much his own poop anymore (ever since I switched him to A/Z), but my other dogs' poop, they still eat regular yummy stuff.... I watch him like a hawk, but he's so sneaky, he pretty much waits for them while they do their business. He can smell it even before it's comes out. He's a little poop fiend! (Sorry if I'm being too graphic, I don't know how else to explain it, I feel so helpless sometimes
) I've tried pineapple (chunks, both fresh and canned) DisTaste, A1, Tabasco, consulted my vet, you name it.
