5 month old Pit/Lab puppy

For sale is half pit half lab, she is a good puppy but she is equipped with a few issues, she's allergic to grain, i really am having trouble putting weight on her, I am currently feeding her all kinds of cheese, rice and chicken and it's starting to get very expensive. She doesn't do well with cats, she is great with dogs but is very aggressive towards cats. She is an extremely high-spirited puppy, so she's very excited around children. And although I'm able to have her outside for hours jane is still not fully house trained. She is spayed plus chipped but i haven't registered her chip yet. more info (719) 244-4161
