lately i'd say in the past week or two tyson has gotten bad about mouthing. im getting very frustrated with this behavior and am at whits end. he spends about 6-8 hours in his crate while we are at work. when i come home i let him out to go outside and do his business then come back in and he just kinda hangs out, laying down, chewing on a bone etc etc. then it seems when my GF comes home he is a different dog. he is hyper, into everything, mouthing anything just to get attention. so then he goes back into the crate. then ill let him out and we will go outside to play ball, or just enjoy the whether, he is usually good outside so thats not a problem. then after dinner (he is crated while we eat) we go for a walk, come back home and he is even worse because this is usually about the time when we are getting ready to relax before bed, so then i crate him because he will absolutley not chill out. the even worse part about it is that he has had a bumb right front leg due to a sprain (so the vet says, i dont trust doctors or vets) so i have to be carefull how much stress he is putting on his elbow which makes it hard for me to wear him down!! so here i need some help and some questions answered. how should i deal with this and when is crateing too much?? i really want his elbow 100% and yet i want a peace of mind without feeling guilty because i feel he is in the crate too much.
