I'm an unexpected owner - please help
Three days ago I "inherited" a 13year-old miniature schnauzer. His owner was a 95-year-old woman who could no longer care for him, and he spent two months in a kennel before I could get him from 1,800 miles away. I know the previous owner frequently fed him from her plate (he begs) and he did not get much exercise as she could not. Therefore I have been unable to get him to eat anything although he drinks an awful lot of water. He was groomed and had vet trips before I picked him up. He is very scared.
I am at a loss as I have never owned a schnauzer. Does this breed need sweaters outside? Are they not lap dogs? Can you teach an old dog new tricks (training)? Any advice would be appreciated.
