Glad that your meet up went well! 30 pounds sounds tiny, especially for an EBD, but I am no expert! My one year old weighs 61 lbs! I have seen several ads of Bullies for sale,
that are advertising "mini" bullies-but AKC says there are no such thing! So I assume that there are just some smaller bullies. I know some knowledgeable breeders on here will have info for you. I would assume it all comes down to how you LIKE the doggie, and if they get along well. Best of Luck whatever you decide. I believe the tails that stick up are called "gay tails". Easier to keep CLEAN!!
