Iggy is 8 months now and has not outgrown this. Barks constantly (and sometimes pees) when I leave him alone.
He can go all night in the crate, so I know its not a bladder thing. Whenever I leave him alone in the crate he will bark and cry forever! He will bark and pee in the SUV when I leave the truck. Every once in awhile, as a test, I will leave him uncrated when I take the trash out, run to the truck, etc. He will bark and bark, if I hear him stop barking, I know there will be a puddle in the entryway. This has got to stop. I don't know how to correct it since he only does it when I'm not around. Tried the bark collar. That worked for a week or so, now he powers through it.
