Regular collars pose just as much of a risk to dogs as they do to cats for the same reasons of the collar getting snagged on something an strangling the dog to death...

for those who wish to keep collars on their on their animal(s) there are collars that are designed with specially made buckles that will release when a certain amount of pressure is applied to it freeing the animal instead of strangling it.
