I just rescued a beagle blue tick puppy mix and I've tried every thing including; giving her multiple baths, all different kinds of dog shampoo and deodorant collars to remove her weird smell, nothing works... what else can I do? :confused:

My first dog was a blue tick mix and boy did he smell. I was not used to being around animals so I guess I was really sensitive to the odor. I bathed the poor thing to death. The odor never left him I just got used to it. My son used to say he smelled like cornbread and loved the smell.
Now to answer your question, I guess you could get doggie perfume or rinse her in a mix of vinegar water... vinegar is supposed to take any type of odor away... make sure not to get it around his face.
Just be careful that you don't cause her skin problems from bathing her to often. Watch for itching, red or scaling skin.

What's the diet like? Have you asked your Vet?

I have a dog who smells just awful.. She is releasing her anal glands. I use lots of frebreeze on the furniture, and bath the dog a few times a week.
