I hate those damn things. Always felt sorry for my dog when dove hunting. He was all about the trip out to pickup the bird, the burrs didn’t seem to phase him. But, the retrieve back to me had him tip toeing and favoring one foot or more. I’d have to pick burrs out of his paws. I worked on toughing up his feet but never got him there. I was considering boots for the dog but just didn’t hunt those types of fields all that often.
