Hate to hear about your lost but to give you the warm fuzzy about the pen. I pretty much recently raised five puppies @ Joe's from the puppy pen to big pen as of today and never brought them no where else due the way I work They just turned year old @ the end of last month I run all my grown dogs in big pen I personally never had a problem but a few fleas
I put them in about ever kennel they have. But this weekend was tough one I hydrated my gyp after the first, second and after the third hunt thanks to some advice besides being wore out she's doing good as of yesterday
Had the same problem at the big pen in manning. The vet told us that this time of the year the briars are full of poisons that can kill dogs especially after 3 days of running in them. We started giving antibiotics before an after a hunt and had no more problems
