Need advice from Rottie owners
This weekend we will be jam packed full with boarding dogs. As of today, two are Rotties...Midnight (an older female) is calm and sweet and very easy to handle (she's boarded with us before) The other is a male who is barely a year old named Rayban and he's barking at me viciously, growling and baring teeth when I stop by his run to say hello. Everyone is scared of him and I have to handle him this weekend by walking and feeding him. I would muzzle him to walk him, but honestly, due to his behaviour, I'm afraid to get close enough to muzzle him! He's THAT scarey! I'm not sure how to go about handling him. His owner put him in the run at the end of the day when they came in, so I've only attempted to take him out once but he was SO vicious, I just left him be. When he isn't snarling, barking and baring teeth, he's watching me with this almost crazed look in his eyes (distrustful and ready to attack look) I'm really not sure what to do! Any advice?
