I have a 1 1/2 yr old staffy x rotti, and an 8 mth old staffy x jack russell. The Rotti x (Sass) is barking while we are out, be it during the day or night, at apparently nothing. There is a small amount of fence barking when we are home, which she get disciplined for, but when we are out she is barking a lot according to my back neighbour. I have tried kong toys and bones. I have just tried with a vibration anti bark collar, which seems to work ok when it is on, but I have to put a muzzle on the younger smaller dog, Jonah, to stop him from chewing the $80 collar off the other dog, and he then whines. I am at a total loss at what to do, I am stressed all the time and worried when I am out. I am not sleeping properly because I am worried the dogs will make some noise. I can't visit my family in Melbourne, because I now can't leave the dogs. It is day's from 6:30 til around 5 that I am out if I am working, or evenings from 5 til 9 or so. There is no where indoors they can go, especially for that amount of time and there is no garage. I have been keeping in contact with the neighbours and telling them all that I am trying to do to solve this problem, but so far there is no joy.
