Bonded pair, seeking advice.
I have a bonded pair of Cane Corso. My female is 10 years old, and has started a slow decline, presenting doggie dementia. She is still happy and wagging her tail, but slow to get up, sun downing, relieving herself in the house/getting into trash (totally abnormal) and is starting to moan at night. She is under the watch of a vet. The inevitable is coming...
My male is 6. He KNOWS she is unwell. He has started looking at me with a face of dread, I kid you not. He has started marking her, literally. He is also marking their entire perimeter, whining at me occasionally, and he will frantically search for her if she is not in the room. He has started breaking out of his kennel to get to her, which is something he has never done.
I am honestly so worried about him. I wanted to post here and see if anyone here had a bonded pair in this situation, and ask if there is anything that I can do now, and after, to help my good boy. I am concerned about major behavior changes and was hoping someone could advise.
I know that he is going to need extra everything, but has anyone here gone through this or have any advice for me?
Thank you in advance, I appreciate it.
