I have two dogs (pitbull lab mixes) if I tie them up one will slip her collar everytime no matter what. If I put them in a kennel (10 x 10) the female will somehow make a hole in the fencing and escape. Can't really afford to buy a lot of fencing right now to fence the yard. Are there any other possible options then taking them out on a leash? I'd like to not have to stand and wait with them as I have two young kids in the house waiting on me. Any ideas or solutions that may work?
