[&:] My black lab (all 115 lbs of her) is also a house dog, but loves to terrorize the squirrels in the birdfeeder. She cuts her pads often. She is laid up as we speak from an injury day before yesterday.
My vet gave me a bottle of PAD-TOUGH. It is a spray with aloe and Comfrey. It is a protective covering and toughening agent for Dog's pads. It has alcohol in it also, so it stings pretty bad when applied to a cut. It stops the lab from constantly licking the wound, thus giving it a chance to heal.
Hope this helps!
