ok so heres the deal. 3 months ago i got a dwarf bunny. me and my girlfriend have desided that we want another one to have as cage buddies. i just found a dwarf i had purchased and have on hold (they are holding him for 3 days because they just got him themselves today) he is alittle big smaller than my one i currantly have. will that cause problems. my bunny i have now is a matured male(i think he is fully matured you can see his testicles if you look) do you think my old bunny will be bossy seeing i know that if they are not nueterd they can get aggresssive...
also on another note he seems very laid back i take him to hangout and play with a shitzu and he just chills and doesnt even bother with him and same with our st bernard.he also never bites.

also seeing my bunny now is litter trained will we experience touble with him maybe trying to mark his territory?
