Canadian Geese are afraid of dogs by nature. My Uncle had about 6 of them nesting on his pond and one day he heard a ruckis and saw somebody's dog barking at them. He went down to pond to chase off the dog and while he was yelling at the dog the drake ran up behind him and stuck it's head and neck out between my uncles legs and started giving the dog all kinds of "H". One of the funniest things I've ever seen.
I think your little daushound would have held his own.
If you ever get a goose problem get yourself a Border Collie, their crouching and predatory stair just drives geese nuts and scares the heck out of them.
We use them around here in North Carolina to chase geese off, they don't even have to do anything, just be there.
