My name is Leo!

We got Leo 6 years ago from Puppyspot and since then he was an endless source of fun and laughter. 2.5 years ago we had our first son and they were best pals since then until Leo attacked him a month ago. We were hoping to fix that until another bite happened so it is clear now that Leo needs a new home, preferably with no small kids. However he's very friendly with adults and when we have guests he relentlessly bothering each and everyone to pet him. He's home trained and overall well behaved but as a dachshund he can be a stubborn one and finds his way around (no sleeping on a couch? No problem! I won't do it while you're looking, but once you're gone...). He's also good with other small and medium dogs but has issues with big breeds as he was attacked by one years ago. He can be loud, but again, that is just a classic dachshund. He's not neutered because of the complex condition, one of the testicles never dropped so he needs an abdomen cut.
