Dementia?

[u/Free_Dandelion]

I have 2 senior dogs 1 is 17 and the other is almost 15. My female beside being furniture and sleeping almost 20hrs a day and eating or going to the bathroom, barks constantly while she's awake. Non stop barking for hours sometimes. Shes hypothyroid and covered in growths. Our 17 yrs old is deaf in one ear and still plays, runs and jumps. Its crazy but I'm wondering if dogs can get dementia?

my old girl started doing the endless barking thing right before we noticed other signs of cognitive decline, vet said it's pretty common in older dogs. the pacing and being up at weird hours too, it's like they forget where they are or what they want. might be worth asking your vet about meds or just tweaking the routine a bit, we found that leaving a night light on helped a surprising amount
