Dogs Clothes

I need to buy my Chihuahua a coat for winter because we live in a very cold area and people tell me I will need to buy one. I also would like to buy him some cute things without spending a lot on “doggie clothing”. I am not a paris hilton doggie in a purse type of girl I just think it would be cute…
I want to buy baby clothes because they are cheaper. because the ones at petco etc are expensive…

Most clothes at petco fit smaller large dogs but they don’t fit my 2 dogs.
1 weighs 71 and the other weighs 110(should weigh 88lbs).

I’ve recently begun to see dogs in strollers and in snugglys like the ones babies use. I’ve always known that people will buy things like coats and sweaters for their dogs when it’s cold but it seems like dog clothes are getting more and more expensive and less and less practical, like doggie tutus. Have you noticed this and what do you think?
