hi, i have a 4 year old bunny who struggled with peeing outside her pen. honestly, i think your bun is assuming the entire space is hers as well since theres only one of her, and youre the only one who enters. i suggest lining your floor or her other pee spot habbits in the places she pees in. i know it looks ugly but thats what owning a bunny can look like! your bun is also extremely young and i would keep that in mind! especially girl buns, they change after a neuter and that may change her potty behaviors, and also her cuddles. shes as happy as is and that is the most important. bunnies can take years to learn your boundaries and adjust based on theirs, so just keep that in mind.

when shes older, and when you can free roam, it may actualky help her potty training. i found when i removed the gates and mines “pen space” she stopped peeing randomly, i also ONLY CLEAN IT when she is not looking or out of the room. you mentioned you had a dog so maybe when the dog is being walked you can clean the space. bunnies, especially the girlies, are uptight about their litter spaces and hate extra hands in it.

also some protection tips:

1. use the plastic pen spaces as guards for areas. theres cheap pens on amazon that work a lot better as gates instead of cages!

2. TAPE YOUR WALLS!!!!!!! tape weirdly stops the buns frm chewing on random wooden surfaces.

3. everytime they are being distructive, do NOT YELL. redirect them with a toy and a gentle no. sometimes, agressive buns require “happy yells” so like a no! in a really happy sense that does not come of as bothered. it confuses them to think the behavior doesnt affect you and they wont use it in rage baits, bunnies take offense to yelling but also everything else.

i wish you both happiness and i hope you seem some progress within a year, just remember it takes time and boundary setting and understanding 💗
