My own dog/puppy fever

I need my own dog🤦🏾‍♀️I love animals and Children. And Everyone has one the other or both. My mom has puppy and my older sister.. my sister has my niece, and niece has a puppy. Here's the part that get on my nerves... I pup sit Alot, meaning I have them Alot, so I train them to make it easier but it's simple things to help keep them from acting out. Well when my mom and sister come in... Everything I teach them "I don't want them doing this do it this way. It's better" for who?? "You have to stop them from barking!" I'm sorry but I apparently don't know how... I get anxiety. And if I cry both of the puppies will come and lay with me, it helps. But I know if they wanted to All they'd have do is call them back. I know they won't, but they can if they wanted to. When I told my mom I wanted my own dog. She ask "why do you want a dog? we have 2".... I'm feeling like (No you have one and you have one. I have no say so, I have suggestion.) I didn't say or think it. It's how I felt. My Mom knows how I feel about puppies. And I'm waiting until I'm able to afford to take care of my own. Also the breed I want my sister. says no... Well I'm surprising her as soon as I'm able to. It's hard for me because I can't train I can't spoil and I have to ask "can they have?" Or "he wants a..." They can simply say No. so now I have to sit there eating with 4 little eyes just staring at me. Laying on my leg and I taught them please🤦🏾‍♀️. When I was younger I looked at it as Aunty. I don't care. what rules? we can play fetch in the house. go get it! Now that I'm older I feel like a mom having baby fever but I know I'm definitely not ready for children yet. But I am for a puppy I want my own. I'm having puppy fever 🤦🏾‍♀️
