Someone is using my company name to advertise their dog outfit . I did a goggle search for my company name i get their ad Q-2

Now you state that "Doggone Couture" is your trademark and your business name, so you may have common law rights to that mark. However, now you state that you use "Juicy's Dog Gone Couture," which may itself be an objectionable mark and not trademarkable because of "Juicy Couture" for human clothes.

You may have trademark and unfair competition claims you could assert against the eBay user, depending on what your company's rights are and what the eBay user's use is, and you still don't describe what the eBay user's use is.

The eBay user may be using metadata in their ad to tap into your name, so you need to contact a lawyer so you can get some specific advice regarding what your rights are and what if anything you should do about this eBay use.
