My name is Ava!

Ava was rescued from being chained without food or water. She is very loving. We don't know her history except that she was adopted from a shelter as a puppy.
We are an older couple that cannot provide what she needs.
Ava is 12 yrs old with very early kidney disease. Needs low protein diet. Teeth are not in great shape.
She has been outside and doesn't want to stay in the house. We have a very small fenced yard and ourHOA does not allow large dog houses therefore she needs someone with a fenced "farm" or acreage. She gets walked twice a day. If she stays inside she must wear a diaper if she is not taken outside every 3 hours. She very seldom barks or lets you know when she needs to potty.
She is guarding with food and will growl or nip. She is a very strong dog. We both have physical limitations and can't take the chance on falling.
She doesn't do too well with my two indoor cats and has nipped at them as well as other dogs on walks.
