My bubbies is 4 years old and is a catahoula mixed. He’s very loving, energetic, and overall just a sweet cuddly boy. He has been through really traumatic situations that has given him ptsd. Normally he’s just timid towards people and it just takes awhile to warm up. My dog and I have been living with my boyfriend for 1 1/2 years now, and there’s never been an issue, they’ve always gotten along super well. This past week my dog has attacked, and badly wounded my boyfriend twice without any warnings. It happens randomly, we’ll all be laying down chilling, and my dog will growl for 1 second and lunge his self and bite him. My boyfriend is not an aggressor. We genuinely are lost, and both scared it’ll happen again at any second. We are looking for advice. I don’t want to lose either of them.
