Logan is a wonderful dog. We have had him since he was a puppy. My fiance and I have had 2 children since having Logan. While he was tolerant for an extended period of time. He began to snip at my 2 year old toddler as he was relentless in his pursuit of Logan's attention. That is something we cannot risk as a family. We attempted to re-home him on one occasion and the individual who took him said he showed signs of aggression. I have not personally witnessed this from him aside from the snipping and when he had an ear infection. In May, Logan's allergies does tend to come up. It normally impacts his stomach and ears. He does have overly sensitive ears as well. He likes to be left alone and just lounge around. While he is crate trained, we leave him out and he does not destroy anything. The one behavior trait he does have is chasing his tail when anxious or nervous. He enjoys bone marrow bones and is currently on blue buffalo food. He is up to date on his vaccinations.
