We purchased a 2 year old bullmastiff male about 6 months ago. He was a kennel dog and had never really been out of his pen much. He is the sweetest most wonderful loving dog ever and quickly fit into our home except for his complete fear of collars. He weighs about 130 pounds and is pure muscle. When you put a collar on him he runs to the far corner of the yard and glares at us the entire time. He won't come back to us and hides from us for days after that. We always give up and take the collar off of him after an hour or so because he acts horrible. Even after we take it off he will avoid us for up to a week and will hardly eat either. When you put a leash on him he yips and whines and rolls over and over and over while biting at the leash. It sounds like he is dying - I'm not exaggerating either. If you even put your hands around his neck he will run and hide and he also knows the word 'collar'. I've thought about a harness but I just think it's going to be the same problem. Any suggestions?
I have never had this problem with a dog, but I have with horses. What I did was every time I was with the horse i took its halter along, I often ran it over his back, neck etc. and then I praised him and gave him a treat. Never actually putting the halter on. It took awhile but eventually the horse looked forward to seeing the halter and left me put it one and then I left it on while I brushed him and praised him. He soon got used to the halter and he looks forward to us coming with the halter. This will work on a dog as well.... kneel in front of him so you don't seem so demanding and give him his favorite treats. persistence is the key :) Good Luck!
what you should do is put it on him about 5 times a day and each time you do u give him a treat or pet him or do something to gratulate him, another thing you can do is have a trainer train him with you . good luck
