<human>: I have a Bluetick Coonhound who is about 4 or 5 years old according to the shelter we adopted her from. She's such a sweet, docile and calm dog when she's around humans. She is very tolerant of little kids petting her and loves attention from adults. 

I've noticed in the 6 months I've had her that she has a few troublesome quirks that I think resulted from her hunting dog training. The biggest problem is her reaction to small animals (birds, squirrels, and cats). She will lunge after them and attempt to tree them (run them up a tree) which is a pretty common practice in coon hunting in our area. She has a fantastic nose, but her sense of smell often causes problems because she'd rather follow her nose than the leash when on walks. She also doesn't like to play with toys. She shows no interest in retrieving or tugging like a lot of dogs I've owned in the past have, which leads me to believe she was probably a dog kept in a kennel outside and mostly used for breeding (she had a litter of puppies at the shelter and they think she had been pregnant prior to then as well).

Does anyone have any suggestions for taking the hunt out of a dog? I feel like I've been getting wrongfully upset with her for things that aren't her fault, just the fault of the person who owned her before me.

Can you give me a shortened version of the text?
<bot>: Bluetick Coonhound likes to tree cats, follow her nose on walks, and doesn't play with toys. How do I undo her former hunting training?
