Like many others who have already commented, I wouldn't trade my Toby for anything. He is always happy, and shares that with everyone around him. He does have a grade 2 luxating patella, so we got stairs for him to use and he has no problems now. He has a few allergies and does the honking/snorting thing at times, so we have a portable air cleaner, and those episodes are far and few between. We just added Rudy to our family, a 10 week old yorkie, and Toby is actually helping out with the housebreaking...yay! They are not for everyone, they can be stubborn at times .... but with patience and persistence they can turn into the best fur companions you will ever have
