I'm not saying this to tick you off even more than you already are but to help because I've been there on other things.
I do have to say - people on this board can be a bit harsh - especially to newbies. We're all human beings & make mistakes, thankfully it WAS his hand & not the other dogs throat. That could have been pretty gnarly if otherwise. But at least He openly admitted he was wrong & apologized. I do think you guys need to communicate & talk about how you feel, it's not worth staying ticked off about if it's something you guys can learn from & move forward from. Being with my man for 5 years now I've had to pick & choose 'the battles' - not all are worth it & we've also had different ideas of how our dogs should be handled. I try not to bring that stuff on an open forum because I honestly feel it's no one's business on here except for maybe the breeder I got her from to get ideas & a professional trainer I hired. They both have been very professional & helpful & don't undermine or even mention my relationship with my now Hubby. The issues stay focused on the dogs & what can be done. When my hubby first heard the ideas from me, honestly he got a big head but once he heard the same information from different sources & other ppl & SAW the effects & changes it made in the dog it MADE a HUGE difference. Some men won't listen to a forum ideas about their pets, especially when the pets are like their kids, which seems so in your case (idk why) - unless it's Car related. Maybe you could encourage him that you both go to a trainer whos HIGHLY familiar with Pits with each dog at different sessions. There are also great books & videos about pitbulls if he's not interested in the open forum - he's already getting a lashing on here & not even a member, who wants to come into that??? Especially when they already KNOW they're wrong.
Your dog charged his - how is that Peaches fault or Riley's? I do see favortism but on both parties here - just to be fair
. No relationship is the same & they all take work sometimes. Shitake just happens sometimes - we're only human. I mean if you know he's that irresponsible, why not bring your dogs along in the first place?
