What to do...

[Lindsey]

Hey everyone... I've had a bit of a stressful week and I guess I'm looking for advice or just to vent a little...
In my last thread I mentioned Kyle. We had been seeing each other for a month or two and then decided to start dating. I really like him. He does cute fun things with me that every other guy I've dated has refused to do. He takes me to the zoo, walks down by the river, bowling, we go out for mini golf and ice cream, he even took me to the wavepool I loved going to as a kid (turns out it's much tinier than I remember and not quite as fun as an adult!) I love his friends and his friends love me, and I like that he tries to protect me and has no problem showing affection to me in front of anyone.
Well all of a sudden he's gotten a grudge against my dog. Layla is my life, we're a package deal. I don't mind if there's little things he doesn't like, because she does get annoying sometimes! But last week it just started where he'd be constantly saying my dog smells bad and I need to bathe her more (I bathe her once a week... she only starts to smell a little bad right before bathtime after she's accidently gotten some pee on her hair, so I've started trimming that constantly to keep him happy). So after that he complains that she still pees on pee pads... well excuse me but I'm at work all day and she can't hold it that long! I also don't have a full fence around my yard so anytime she has to go I'd have to put on her harness and leash and walk her around the yard. The pads work for our lifestyle. So then he complains that she sleeps on my bed! We've had at least 3 blow-ups in the past week about it, and last night I couldn't take it and said "Just leave" and he walked out of my house and drove away.
I don't know what to do. He texted me as soon as he left and said he doesn't want to fight. I told him I wanted to talk. We drove around for awhile and parked and talked. I cried a lot. Basically he said he doesn't want to fight and he wants to be with me but he seems to get more and more annoyed everytime he sees my dog. I don't want to break up with him because he really does make me so happy whenever he's not mad about my dog. He said he'll just try not to be so vocal about it but is it going to be any better if he's just keeping it all inside? I'm confused and I don't know what to do about the situation
