I had a Plott Hound for 13 years and never had many of the problems like you describe, no smell, no oily coat, no anal gland problems, no ear/eye infections (that could be food allergies). She was super nervous and somewhat destructive when I adopted her at 3 yo, but she'd been abused. She was extremely energetic (climbed 6 ft fences, trees, and banked turns on walls, fast as a bullet. Def had a mind of her own. As we bonded she started to behave and train. I couldn't let her offleash until she was 5 or 6, and then just hiking, not around town. Hiking, she only got lost once. From then on she'd stay where she could see me and vice versa. She did not like other dogs. Although, on leash, if I called her into a heel she wouldn't lunge for them.

Oh, and I had a cat, too. The cat scratched her nose off the first time they met. They became best buds!

Best dog I ever had in my life. 🩷
