We have a young male Husky/German Shepherd mixed breed. About a year old, pretty good size. Let's call him Tobias. He has a friend, an older male Alaskan Malamute, named Titan, who is about 5 years old. They stay in the home a good part of the day, and go out together about 3 times a day.
Often when they are outside, Tobias will begin barking for long periods of time and for no apparent reason, which of course often ends up enticing Titan to bark as well. We moved into a pretty large neighborhood a few months ago and we are afraid we will start getting complaints.
We have tried to narrow it down to what causes Tobias to bark, but have not been very successful. Sometimes it is a passing pedestrian or bicycle, but even something so trivial as a newspaper page or plastic bag in the yard blowing in the wind will trigger the barking.
Tobias gets excited very easily, although he is not mean. He won't even hurt cats in the house. Outside, he is on a zip line spanning about 30 yards. Titan is on a fixed line tied to a nearby tree. They are long enough for them to meet to play, or spread out of each other's reach. I drew a quick illustration.
The previous residence was on a farm, and they were staying outside pretty much all the time, in a large fenced area with a dog house big enough for both. I remember him barking at deer and other animals fairly frequently, which is behavior I would expect, as Titan did that as well before we got Tobias in there. The area was not close to the road and did not see much foot traffic.
We are not sure if it has to do with Tobias' breed, if he is just twitchy or if we need to change their positioning. Any suggestion as to how to change this behavior is highly appreciated!
