STAYS FREE OF LINT AND PET HAIR!
Size: Large, Style: Tall, Color: Black
Busy bartender with black uniforms and white dogs. THE STRUGGLE IS REAL!! I wore them all week. Pet hair brushed off with ease. Remained wrinkle free, nice flow and feel. LOVE ALL THE POCKETS!! LOOK GREAT! Haven't had the misfortune of the DREADED BLEACH SPLASH....hoping the fabric blend will prevail! Will order a backup or 3 ;-)

My picky dog loves them.
Size: 3.5 Ounce (Pack of 2), Style: Chicken Chips, Size: 3.5 Ounce (Pack of 2), Style: Chicken Chips
I try to give my dog, whom I love so much, the healthies food and treats that i can. She is so very picky and it's difficult to find things she likes. She loves these treats and expectes one every morning. She litterally waites by the pantry door for one. The are healthy Human grate chicken chips. Makes me feel better about giving her a treat. I would Highly recommend.
