Hello! I'm new here. We have 2 pitbulls-a blue nose(female pure breed) and a red nose(male,not registered). We got the rednose when he was 6 weeks old and we got the female 5 weeks later when she was 6 weeks as well. The grew up together-same kennel,sleep on the same pillow together,sleep with me together. Everything was ok until the female got her first heat. We separated them because we didn't want to breed yet. One of the days she was still in heat, the male somehow got in the house and they got into a fight. We managed to separate them before any damage was done. Few days after her heat was over we tried to put them together and everything was ok until one day my husband decided to give them some treats and he put one in one corner of the room and the other end of the room, the male is a piggy (lol) he finished his treat first and then went to the female to try eat her's. And this is when she snapped on him and they started attacking each other pretty aggressive. Ever since they can not get along. We can not figure out the reason. Can anyone help me? What can we do to bond them?
