I can relate to your problem. We also have a large walnut tree in our back yard. Yesterday, unfortunately we had to let our Coc-a-poo of 16 years go. But, it was about 8 years ago, he was chasing our new Dalmatian guest.(she has now become a family member.LOL)..around the tree, and he let out a huge yip, and then came hobbling over to me. Well, he had slipped on one of those walnuts, as you said, they are just like small tennis balls, with that, we made a trip to the DR, and he had to have a very costly Knee surgery. Dr. said it was the same as an athlete has. He came made it thur the surgery fine. And had many more happy years. But, from then on, the walnuts had to be cleaned out of yard. What a job. I just thought you might like to know. (rather early for walnuts though, at least here in Michigan they are not dropping from trees yet).
