Good Afternoon and welcome! I am Dr. Loretta, a licensed veterinarian and I am happy to answer your question.
I am so sorry but Sally is not available but I would like to help.
This behavior is due to the stress of this new environment and this is causing anxiety to Bentley causing him to act out. The first thing is to purchase a DAP Collar at the pet store which acts as a calming agent to decrease Bentleys anxiety.
Take Bentley to your vet to be sure there is not a medical cause for this behavior.
If this is ruled out, make sure to never allow Bentley alone in the house near any of the areas that he had soiled. Renewing the crate training will really help so that you can get him out as soon as he wakes. If you see him doing this , do not discipline him and then when he goes outside, praise him profusely and possibly give treats.
Remember, this is caused by anxiety and not bad behavior so the point is to decrease his anxiety. Your vet will have anti anxiety medications to help if the DAP Collar is not enough to get sweet Bentley past this. Keeping Bentley in a crate or on a leash and never leaving him alone in a room will get him back to what he used to be since the anxiety will decrease.
This LINK will explain in more detail.
Does that make sense to you?
Please let me know if you have ANY other questions. My goal is to give you 100% satisfaction and if you are not yet satisfied, please REPLY so I can clarify for you.
Sincerely, ***** *****
