moved back in with parents been here 5 months going crazy pretty long?

In Feb. my husband myself and our 2 dogs moved into my parent's house to save up to buy a house and they're basically driving me crazy! I'm constintally getting yelled out by my parents about my smaller dog becasue whenever my brother is around she'll bark at him and she barks at him because he likes to chase her around the house and scares her (he's not a kid either he's 24) so i get yelled at to "Shut that dog up!" at least 5x a day yes it's my parent's house and I respect that but they're having financial issues so my husband pays the rent and buys the groceries they pay the electricity and water sattelite and internet. My husband works nights and I wait up for him when he gets home so we hang out watch tv play video games and so on he gets home around 2am so we'll get to bed around 4am meaning we don't wake up until noon or 1pm so then every day i hear about time you woke up and so forth. I had moved out on my own well except with my husband the past 4 years and moving back in sucks! When we go out on the weekend my mom will stay up at night until we get home yea granted she's not tellin us what time to get home but she'll ask me when are you getting home and so forth, my reasoning behind it is cuz she's just being a mom, but it's still annoying to hear where did u go did you go out drinking and so forth. Now my older dog my guess is she's feeling the stress from me so the past month she's been having food aggression issues with their dog and two cats she won't let them get near me if I'm eating she'll bark and snap at them. Not if she's eating if I'm eating. So the other day my dad tugged her fron the back of her neck really hard and made her cry and hide under the couch after she snapped at their dog. Which I know she shouldn't have snapped but it still really pissed me off. Then it's having to hear my mom every day complain about my dad not finding work and i don't know where I'm going to get money from to pay this bill and such and I've told her if u need money let me know and I'll give it to you it's not a big deal, but every single day then she'll say maybe i'll look for a second job from 3pm-midnight and blah blah blah but never does and she knows she doesn't have to. I've told her i really don't want to hear about your financial issues and issue with my dad i have my own issues to deal with i don't need to be thinking about yours. It's worse now because it's summer so I'm not in school or work (i work at a school and so does she so everyone is home all day everyday but my husband and brother) My dad hasn't worked in 3 years because he can't find a job my mom and myself work at the same school so we're out for summer and I'm in colleget too but it's summer so I'm here with the two of them all day. I've told my husband I'm going crazy here and he'll tell me just a few more months because a bank wants to see 3 months reserve and so forth so he's planning on moving us out in January or so but he doesn't really see how it's driving me crazy because we'll wake up at like 1pm and he leaves for work at 330pm and gets home once everyone is alseep. So my question is after that long novel haha is How can I either 1. talk to my parents in a way that they won't take it the wrong way that they're driving me crazy and yes I am living in their home but I'm also paying for all food and rent so don't treat me like I'm 16 or talk to my husband about moving out because they're driving me crazy. And moving out and renting isn't an option because he doesn't want to rent anymore he wants to buy something but we're still about 6k off from where we kind of need to be to buy something decent and get a loan for that's why he wants to wait another 6 months to move out.
