I am new and I have seven month old Rottweiler mixed with Pit-bull that happen to whines all the time. Also after a being exercised we cannot leave her alone because she will chew up on the couch. We have taken her to some training classes where they would help us but it didn’t work. We have tried stuff like bitter apple spray but she loves it. We also baby sit a friends dog on the weekends to comfort her. She will not whine just chew on the couch to destroy it. She also will not sleep through the whole night always waking up at 4am and then starts barking for us to take her out for a walk; it’s kind of hard to ignore when her bark will wake up our neighbors, so I go to let her out even though I know I am suppose to wait until she has calm down. Giving her away is not an option she is family but I just want to fix these problems please can someone help.
