That's so funny, they sure can act tuff, I have said if a predator ever got a look at what was barking and keeping them away they fall over on their backs laughing. My mix bird dog thinks she is a doxie too. I do think they keep alot of preds away during the day, at night we never hear a peep from them they are all covered up in their beds. lol good thing our flock is locked up tight.He bluffs who he can but when the rottie comes along he is a real weinernow the younger dogs think he is a killer but Tobie knows his place and who he can dominate and who he can't, he gives the big dogs any trouble and the males will try to pee on him
but if he is inside that glass door gives him lots of courage and he is gonna tear them up.
had to join in and share, she is always by my side.
