My son adopted a 3 - 4 yr old GSD from the shelter. They clicked right away- almost as though the dog had been with him forever. Well, he started a new job (just got out of the US Air Force) and decided to crate the dog. He started with five mins, then 10 and 20 mins. Then went to 10 and 20 mins in the crate and my son outside of the house. The dog tore the crate apart!! Heavy duty wire crate with wires all bent apart and destroyed- in 20 mins. So he goes out and buys one of the airline approved plastic crates. Same thing- door completely pulled into the crate. So now he puts a muzzle on the dog, resecures the door with industrial strength zip ties, and goes outside. Within a half hour the dog shows up in the front yard. The dog removed his muzzle, tore the crate door off, opened a sliding glass patio door, climbed a six foot fence and went out front to be reunited with his "Daddy"! He took the dog to the vet with pictures in hand of the crates to see if the Dr. could give some mild sedatives or something until the dog gets used to being alone. Doc says "that is animal cruelty to crate him against his will." Son said "this visit is over". I HAVE NEVER SEEN A DOG WITH THIS KIND OF DETERMINATION!! ANY SUGGESTIONS?
