Anybody know a supplier of wooden/heavy plastic 'off the shelf' dog kennels in BKK. I cannot find even in JATUCHAK MARKET! Help very much appreciated.

There are at least 3 pet supply stores on Chok Chai 4 with kennels outside for sale. Have never looked closely but most appear to be wire types but they may have others. Suspect an experienced taxi driver might be able to direct you to a local store as they are quite obvious being outside on sidewalk. Or any Vet.

Here ya go.

12Call's link is all wire-mesh ones also.

However, wouldn't a wooden (or plastic) box in the sun get rather too warm to be comfortable (unless you're putting it in a shady area). A wooden kennel sitting outside might also have an issue with termites.

If you still think it's a good idea - best bet is probably to get someone to make one for you. (If nothing else, it's very cheap to get things built here...)
