My bulloxer is 4 she is a great dog. I have no complaints with the breed, shes very friendly,I have 2 kids that she plays with has never shown any aggretion with them or with new people.However i dont think there ok for an apartment.There a big dog sometimes clumsey,and need some room,and a fence,mine likes to be curious.Her sire was a american bull and her mom was a boxer I wish I never got her fixed cause her pups would be beautifull...
