...plus they are definitely mutts but they are going to be big mutts. I think it's the weight plus walking on hard ground that aggravates things like dysplasia too, I know some of it is genetic.
John, you're welcome to bring them out occasionally to run in the fields. It would give you an excuse to go to Hillside for a coffee.
Might do that later...right now I'm having a job persuading them not to eat dirt, chew shoes, plants, etc or steal my socks and to stop barking at rocks.
The more mutt the less chance of genetic/breed related stuff like hip dysplasia. But that comment is too late as you've already got the dogs. Personally, I just set aside one of my 6 mm or 30-30 shells for issues like that. Sure I love my dog, but it's just a dog. They make more just like it every day that need rescuing. Flame suit on.
