Need rehoming

Zoe is an 8 year old female beagle/chihuahua mix. She weighs around 25 pounds and has short hair. Her coat is white with a few brown speckles. She is smart, loving and loyal. She will try to get on your lap as soon as you sit down. She can be very active or passive depending on the owner. She is good with children but hasn't been around any for a couple of years. She is very timid and needs extra time to get comfortable. I need someone who is willing to work with me and her. I have a professional trainer that will help as well. She's a great dog but because of physical and mental issues, I have to find her a new home. She's up on her shots and is chipped. I can send more pictures if interested.
