I'm not sure if y'all remember my bulldog/ridgeback mix Buckshot, well for the past eight months or so, he's been "losing his mind." I brought home a Amstaff to foster and they tied up together, Buckshot didn't want him close to me, and ever since then he has been overly aggressive.I've got two bulldogs that are purebred and he's my mutt, my two other bulldogs, Gator and Bambi, both have good temperaments, get along great, and play good together when I let them off their chains. However, when I let Gator off his chain, Buckshot has to stay on his otherwise he attacks Gator. Today he tried to jump on my female, Bambi, then attacked Gator when Gator got too close to his chain spot, and when I went tl correct him, he barred his teeth AT ME! I was half tempted to sho him right there on the spot, but damn, I've that dog from when he was 5 weeks.Im almost 7 months pregnant and with my baby on the way, I feel obligated to either shot him or give him away. He aint neutered, but he was fine as an unneutered till I brought that Amstaff to foster. Ever since then, he's become more and more aggressive.Would it be best to put him down, or neuter him and wait?
