My name is Diamond!

Hello. I got my pet from my grandfather when I was around 12 years old. She is a little on the older side (around 12/13 years) but she has a young heart, moves around well, and is very playful. She is extremely healthy and has no issues medically. I want my dog to have a safe home and to be comfortable. She does have behavioral issues, unfortunately. I am here to be honest- she does bark around new people, she tends to growl sometimes, and she has snipped before (not random strangers but me). Occasionally she can be rowdy and have an attitude. But most of the time she is calm and will walk around the house, relax, and look outside of the sliding door. It will take her some time to warm up to new people, at first she will be alert, but when she does she is sweet and very calm. She will let you know when she wants to go outside and come in. She is protective but also a scaredy cat. I am a college student/work 12 hour shifts. I am unable to care for her properly. Need someone patient.
