Are your chi's big ones or wee tiny ones? Do you know what size they are? My Boston outgrew her puppy shoes from last year and needs a new pair. We live in the city and they salt the sidewalks so all 3 dogs need shoes in winter.
they have soft rubber type soles not cloth the chi i got them for weighs 7lbs they fit but she wasnt havin it they are a lil over 2" long and a lil bit over 1" wide id think they would fit a bosten terrier but im not certain cant be sure if the soles are water proof either just that they are rubber like material
