My name is Koda!

We adopted Koda from a shelter in 2021. He was a stray so there wasn’t much info when we got him. He is around 5-6 years old. He listens most of the time. He does know “lay down” and knows that he’s supposed to lay down in a specific spot. He loves to be outside running around or even just laying in the sun. He needs to have either a fenced in yard or an invisible fence of some sort as he will take off. Koda is well mannered while inside. He was crate trained, but hasn’t been in one for a few years unless he stays at someone else’s house. He has recently started to become aggressive to our other two dogs. It isn’t all the time, but is enough to be concerning especially with our infant son getting to the point where he could start walking at any point. Koda cannot be around cats. He is very aggressive towards them. He would do well as an only pet. He has done well in the past with children around 3-4years old and older but is unsure of our 10 month old son.
