IMHO it is quite impossible to teach a Shitzu to do anything at all. Horrid creatures.

First three on the list probably right, then I'd have put lab. I think Min poodles are usually brighter than standards.

Belgian Shepherd (any type) could have been on there too, and while have no evidence I'd expect the Akbash and Karabash to be candidates. Other possibles might be Welsh and English Springers, and Irish Water Spaniels.

I don't think the McNab is recognised by the Kennel Club.

How about the bottom 10? I'll nominate Bonnie, my late Great Dane, any my stepdaughter's Otterhound as both unbelievably stupid. Oh, and my late friend Marianne's Shitzu that we dubbed a shitty-sue as it preferred to crap on her bathroom mat. Cassie (Hurwyn Calypso at Lokmadi) our first pointer bitch was very stupid, but her pup Puff (Germal Puff'n'Stuff) was very bright indeed.
