Hi everyone, my maltese approximately 13 years has started being active at night, all night. She was recently sick, https://www.petforums.co.uk/threads/senior-maltese-losing-weight.471881/#post-1065091082 off her food and lethargic, had her teeth cleaned and a benign tumour removed and after a change to chicken, veggies and brown rice recovered beautifully. Its great to see her happy again. Now every night i wake up with a maltese on my chest her favourite toy firmly held in her mouth tail wagging wanting to play. Over and over. She is happy but obsessed. The only other 'symtom' is panting at odd times, her heart and lungs appeared fine to our vet and her recent blood tests cleared her of cushings disease and a bunch of other things. In all other respects she seems well. I don't know if she is just feeling better or is this doggy dementia starting? Any ideas appreciated.
