Sudden onset separation anxiety/ dementia?
Our almost 10 1/2 year old female has suddenly become anxious as we have left the house. We have a 6mth old GSD puppy and a 6 year old mixed breed dog. Puppy is crated downstairs, 2 older dogs upstairs in our bedroom (in the A/C). That room has been kept dark with room darkening shades. Over the past couple of weeks, our old girl has been whining more when we leave for work. Also, early in the mornings, she has begun waking up early, pacing around the foot of the bed for a few minutes (almost like checking in with everyone). I think she's been more clingy with me lately, too.
Then a week ago, she had a big poop accident in her crate, we were gone for about 6 hours and she was a mess. All bedding was washed and of course she needed a bath. The next time we crated her, we were gone for a few hours and she broke a rod on her metal crate and chipped her upper canines. We tried a treat filled kong the next time we had to crate her and that eliminated the stress at our departure, (we set up a game cam to watch what she was doing) but after a couple of hours, she started banging at the crate, moving it around and breaking the drywall behind it.
She has never had a problem staying in her crate, has always had a sensitive GI system, has never been a fan of other dogs, but does like and play with the puppy.
I ordered cholodin for dogs on Amazon. Any other suggestions? Does this sound like the start of dementia? Have you experienced anything similar?
