I currently have an 80lb lab that is really poorly behaved. He's chewing couches, clothing, jumping on counters, humping etc. I tried to tire him out in the yard but we're currently experiencing downpours and outside isn't an option. He doesn't respond to "No!" and barely responds to his name. He is extremely friendly however and that is not a concern in the least. I have him until 630 this evening and am supposed to sit him tomorrow too. Please help!
