Dog Walking Playgroups Pet Sitting and more! Four Paws and a Leash is a fully bonded, insured and licensed Boston pet walking and in-home pet sitting service. In order to set ourselves apart from the rest, we have set higher standards since we first started in 1998. We enlisted the services of the American Red Cross to become certified in pet first aid and CPR and are members of Pet Sitters International. Four Paws and a Leash is an excellent alternative to a pet kennel. While pet sitting we can retrieve your mail, water plants, and turn lights on/off. Does your furry friend need a vacation? We can care for your pet in our home. Four Paws and a Leash in Boston also offers playtime at the park and obedience training for your dog. We care for cats and other pets too.
