They're fine, but not my type.
They are too....breakable to me. I need a rough and tumble dog that I can take anywhere and do anything with.
I don't really like it when I see the 5 pound chihuahuas super overwhelmed with meeting Leo, a medium-sized dog who is just calmly sniffing them. There is just too much that can go wrong in my opinion, when they are so small and everything else is so big.
So, I will absolutely pet and have fun with my friends toy dogs, but I would never own one myself.
