V, Id ask the owners to keep his food at your house for the weekend so if worse comes to worse and he is not happy to see you, at least you could fill a bowl with food and another with water and quickly open the door, drop them down and shut the door so the dog won't starve at least!
I have very little fear of dogs... most of them Im fine with. I get a bit nervous around Rotties... I was bit (VERY MINOR) awhile ago... someone was walking a Rottie around a park and we were all playing a game, well I was one of the first ones out so I was petting the Rottie, but as more players went out they came over, soon there were about 10 people around him and I was the closest since I was first and he because nervous and kind of grabbed my hand in his mouth. It hurt a little bit, but since then Ive always been a little more nervous around Rotties even though I love them! My brother has 2 pitt mixes and 2 of his old roomies had a pitts. All 4 of them are FINE. None have EVER hurt or touched anyone. My bros big girl (90lbs and 7 years old) she is pitt/chocolate lab mixed, she plays with my boys all the time and I have NO fears of her EVER hurting them. My brother has her trained sooo well! She loves children and our friends feel 100% comfortable bringing kids around her.
Don't fear it too much. Im sure Stink will be fine! I love his name! haha
