Yes! I vote getting another dog! My dog Pita is so much happier now that she has a playmate every day. At least she's not alone anymore whenever I leave her for work.
There are a lot of adoption here in Dubai. Besides K9 friends (they're very good) there is also SNIFF, RAK animal welfare society, Dubai animal welfare society. and if you get on the dog groups on facebook (Dogs in Dubai) there are a lot of dogs being fostered and are looking for a forever home,
