Third time I ordered from Animal Den. This time I ordered a small T-shirt and keychain from the rottweiler section. The package came priority mail on about the 3rd day. They are ALWAYS fast. The tee shirt was too small, I was used to ordering their adult sweatshirts which do run generous in sizes as their website claims, so I thought the tee-shirts would as well. I sent it back for a medium. I sent it on a Thursday, and I believe I got an email from them on a Tuesday saying they received my return and my order was being processes. I got my medium shirt 2 days later. I thought the customer service was speedy, and efficient, and once again, I am one very satisfied customer. My advice would be this. Sweatshirts run large, tees run a bit on the smaller scale.
