OK, as a pet professional (18 years worth) I will comment on the breeds listed (my opinion, only)
Chows...........Agree 100%. They cannot be trusted. they may not always be bad, but would you want to tempt fate with YOUR child?

Cocker..........Agree 95%. They used to ba a wonderful breed until over breeding RUINED them. They WILL have one of the following problems, if not more that one:
1) biter
2) bad, stinky, smelly skin and or ears
3) not house trainable (pees everytime you look at it)

Dalmation....all they need is an owner who is in control, not a dog that is in control

Lhasa......bad breeding is again your problem.

Sheepdog.....other than it being a grroming nightmare that no human (except a "show person") can handle I am not sure about them being on this list


Shar pei.....what they said

Akita......see dalmation

Pit bull.........I think this might be reputation alone scaring people

I'll skip the others that were grouped together except
Scotties......I have NEVER met a Scottie that did NOT bite. They all do.

Just my 2 cents
