How long can the Maltese stay alone for?

I have left mine for as long as from 9am-7 or 8pm (which was a really really long time). Your Maltese should be fine as long as it has a wee pad, food, and water. Although I do not recommend leaving a Maltese with anxiety issues alone for too long. The amount of time your dog can tolerate depends on how hyper and calm it is--I wouldn't suggest leaving it for more than 9 or 10hrs (being the very most, and not all the time either). On the average day maybe 5 or 6hrs should be the maximum. If you are planning to go away for a long time, I suggest having your Maltese stay at a dog hotel. :) hope this helped!!
