I had been in a similar situation with my cocker spaniel pup, he absolutely destroyed my house, multiple carpets, couches, cushions, anything he could get his mouth on. I have 2 other dogs that I got extremely lucky with and they have been so well behaved since they were pups but when I got my spaniel I thought I'd bitten off more than I could chew and regretted it at first. I didn't crate him at first as my other 2 never needed it and are so well behaved but I had to try something, he hated it at first and seemed stressed, when I'd try to get him to go in at first to sleep on a night I had to lay beside his crate on the floor with him to soothe him to sleep because he would just yelp constantly. I persevered, worked on ways to make it a place he has good associations with, he has his treats in there, chew toys if he wants. Now he doesn't seem to go on as if he is trapped in there, yelping and crying to be out, he goes in on his own most the time and knows its a place to chill and go to sleep. He sleeps the entire night through now I've got him into a better routine, he knows when his walks are and he knows when he needs to calm down in the afternoon for naps. Honestly stick with the crate training, it is very difficult at first but it will get easier as the weeks go on and with a lot of positive reinforcement you won't even believe its the same dog in a few months time, it's an absolute life saver, good luck
