I need some help/advise please!! My fiance and I just got an almost 2 year old (in May) EB from a lady that didnt have time for him anymore. We went over to her house on Saturday morning and met him, his name is Chaos. He was VERY friendly towards us but they also had a smaller dog that nipped at him when we got there (maybe they were acting out due to strangers in the house) Chaos pinned the little dog down and was growling at him but not bitting him or hurting him...more pushing him around with his paws. Once the little dog was removed from the room Chaos went back to being friendly and playful. The previous owner said that that never happens and Chaos is very friendly towards people and dogs. While we were there we noticied a few different kids coming in and out of the house and Chaos would run up to them and the kids would say hi and pet him and walk off. She said that he does very well with kids also, they had a 7 month old baby that he was very gentle with as well. After some thought we decided to add him to our family. When we went back that evening and picked him up we brough him home and he adjusted almost immediately. At the time my sister and her boyfriend (our roomates), my dad, and my cousin with his 1 year old baby were all in the living room. Chaos went up to each one and gave them all love, he was really good all night and seemed to be fitting in perfectly.....UNTIL....the next day we were in the front yard getting ready to leave and he saw our neighbors dogs, he was sort of puppy barking and you could see he wanted to play with them, it was more of a high pitched squeel and whine. Then we took him to the pet stores and he saw another dog and was growling and barking. We thought maybe he was just trying to go over there and play and as soon as I walked him around the corner he stopped and went back to his normal self...people came up and petted him and he seemed good (someone even had a cat and bent down to pet him and he didn't even bother it). At the next store we walked in and there was a dog right there so he smelt his nose and they seemed ok but the other dog sort of sneezed and then he lunged at him and was barking and growling (no one got bit)...he also did that to a female puppy a couple minutes later. We took him out of the store and left. When we got home later that evening my fiance kids came home (9 year old girl 13 year old boy) he was in the living with me and all of a sudden he went after his daughters feet...I wasn't sure if it was play or aggression but I picked him up and put him in his kennel so we could get a leash on him and slowly introduce them. My fiacne let him out and he went after his son's feet, growing and barking and nipping. We thought maybe it was another dog smell so the kids took showers and changed and he did it again...only while they are walking. The kids sat down and gave him treats and petted him and he was totally fine, he even laid on the couch between them and fell asleep. WE NEED HELP! we want to work with him to correct the behavior but need some advise. Like I said he's almost 2 and NOT neutered...we plan to take him in this week and have that done. Will neutering him at his age help with the dominance/aggression?? Or is he stuck in his ways so to speak???? We can handle the dog aggression and since we have no other pets in the household that would be a simple fix...but the nipping and growing at the kids feet has me on edge...we can't have him on a leash in the living room every day and it's not fair on the kids. Thank you!!
