Honest truth, if I did have one, people in Toronto will 'LTAO' (Laugh their a* off) and personally, I'd find it quite embarrassing. And plus, dogs are dogs, they want to walk and enjoy the fresh air, so I wouldn't buy one or put Missy in one.
No offense to anyone that has one! I just don't think it's right for my girl, that's all. She'll enjoy walking instead.
