I have two dogs. One is five years old and the other is 15 1/2. My five year old is just fine but my senior dog has doggy dementia. She usually does her "sundowning" starting at 3:00 p.m. when I am at work so I need someone to come and stay with her for like 2.5 hours on Mondays and Fridays when I go into the office. She doesn't require walking as she is also blind but just needs to carry her to go potty outside (both dogs are shih-tzus) and make sure she doesn't get stuck between the furniture. Thanks in advance.
