First, in my defense, I waited until the day before Halloween when the costumes were 75% off. Unfortunately, that meant the bumblebee costume that was really exactly Henry was sold out. So you will not need to ask, Henry is a frog for Halloween.
It was either that or a footballer costume. I don't want to encourage aggression - so I ruled that one out. There were a bunch of girlish costumes too, but boy dogies are so easily embarrassed and I didn't want to add something to his background that would require trips to a puppy psych specialist in the future.
I am thinking of putting Henry in the PetSmart Puppy Hotel for our next trip to Eugene. It can be arranged with play time visits and a treat time that looks pretty neat. I checked out the facility and it looks very clean, well organized with lots of workers. If anyone has first hand knowledge, I'd like to hear!
