Thanks for your ideas. I will wash his bedding. Its been a few weeks since its been washed. He's never had any accidents ever in his crate, which has been wonderful. But can't hurt to do this.
Our house has an open floor plan, so he needs some limits. That's why we have always crated at night. Earlier it was a potty training issue, but now its a safety issue because he will definitely get into something. He loves to do anything he knows is off limits and he would not be trusted at night.
He has a full size crate. We had it sectioned off when he was younger, but as he grew, we opened it up. And we have a quilt over the top and sides. He can see out the front, which I think is good. We also have a downstairs crate that we use when we are out without him, but thats not used regularly. He goes in there fine, but responds to treats in there. Hes not crated in the daytime for more than a couple of hours.
He gets alot of exercise daily except on really rainy days. We are retired and have a few acres for him to romp on, along with his hikes with us.
Overall, he's a happy, typical Vizsla, who has alot of freedom-- maybe too much!
Our "grand doggie" - also a vizsla, lived with us for a couple of years, so we are very familiar with the little quirks of these smart pups. But this sudden crate issue has us confused. Maybe we will just have to be patient and stay firm. I don't want to give in, because there will be no going back. He's stubborn!
