I have a 15 week old American Bandogge Mastiff pup that needs to find his forever loving home, unfortunatley I can not offer it to him. I got him when he was 8 weeks old from a breeder. He has had his first round of shots, he will need his second soon. He is unaltered. He is an appricot brindle with a black mask. He is 75% house broken, sleeps in a crate nightly with no issues. He's well socialized with other dogs, cats,and childre. He has been rasied with kids since day one and cats. He knows sit and has almost mastered paw. He is lazy and stubborn at times but that's the nature of the breed. He requires low maint. and minimal activity. He will most likely be 100-120 lbs as an adult. If you research the breed online you can get more info. I am looking to re-home him with a fee to insure that he will go to a forever caring loving home. This will include all his supplies, crate, bowls, leash, food, toys, treats etc... Serious inquiies only please. Thank you !
