I purchased this for my adult rottweiler. Although i purchased the largest size available the paw still does not fully enters the shoe with few centimeters of space left in the front.

It is very expensive. However my rott had paw injury with later became infected so cost was least of my priority. I needed something to protect the wound from further cuts or bruises. Although i purchased 2 pairs i only put on a pair on the front limbs as that's where majority of body weight (55kg) comes. Hence it is a necessity. I had skipped putting them on few times, but the wound became inflamed again. So I don't take my dog out without it ever. He has also gotten used to, he lifts his leg on his own when asked to put them on.

Very useful esp when you take your dog out for walks on tarmac. They tend to get their paws scratched more on tarmac roads.
