My little Maltese girl is 13 and is showing signs of dementia. She sleeps all day and doesn't sleep at night. We give her 1/2 Alprazolam in the evening and again when she wakes up in the middle of the night. Occasionally (like last night) she never settles down. She runs through the house and cries so much that she can't even feel the meds .I don't want to give her too much medicine. I was up with her for 4 hours, trying to get her to sleep. It's exhausting for her and me as well. Anyone else have this problem?
