This may be lengthy. Okay I have two dogs, ones a pitbull (8 months) the other one is a schnauzer (3-4 years). I'm still 14 but I'm worried about them cause I live in Arizona and the weather is extremely hot. I'm not allowed to let them inside cause of my mom. They're basically locked outside with food and water and themselves. They don't see other dogs besides them. When the pitbull was a puppy, we would take him out to other dogs, the vet, where there's a lot of dogs, so he never had a problem with dogs. But now we don't take him anywhere cause he's so big we can barely control him. I have considered selling them, I just don't think I'm ready to sell them. I want to at least try and convince my mom to let me take them inside, to the park, play with them, but she's very had to negotiate with. Please give me ideas on how to convince her. I don't want to give up so easily cause I really do love them I just want the best for them. Help me.

I have a 5 month old Pitbull and a 2 year old Schnauzer. My Schnauzer growls and bites my pit whenever he's about to eat (even though we have two bowls for each of them). My pit never does anything back, he just stays still and tries not to move until I get his attention then he gets happy. My concern is that I don't want my pit to be scared or to one day fight back since he is twice the size of my schnauzer and stronger.. He's also getting bigger. I don't want either of them to get hurt. Is this normal or should I be concerned ? Btw, my schnauzer was the first dog we got before the pit. He's also always aggressive towards other people or dogs. Both of them play a lot together but at times he just snaps at him out of no where. Also, the pit is really sweet and gentle and I don't want my schnauzer to teach him to be aggressive since he is older and was here first.
