Walking a dog shouldn’t feel like an arm workout. Yet many pet owners know the struggle: one sniff of a squirrel or a squirrel-toned imaginary friend, and Fido rockets forward, dragging you along. It’s stressful and even painful for you and dangerous for your dog. In fact, veterinary experts note that “a dog that’s constantly pulling is frustrating for owners who just want to go on a nice, leisurely walk”. Worse, pulling on a thin collar can injure a pup’s throat – PetMD warns that collars put “a lot of tension on her throat… Little dogs can do a lot of damage to their very sensitive throats”.
