I have 4 dogs and wash an enormous amount of linens, blankets and bedding each week. This dryer has a HUGE lint trap and I have not had issues with dog hair not being picked up in the dryer. It would be foolish for me to say that 100% of the dog hair was removed 100% of the time. I can say that 100% of the time it is rarely or ever noticed, and I can't say that it didn't get picked up in transferring it from the laundry room to wherever I fold and finish.
The lint trap is like a basket, rather than just a screen and it holds twice as much. I had the same reservations about this dryer when I read the reviews before purchasing, but after reading a ton of reviews on other various models, determined that given the size, price point and features, it was worth the risk.. and after almost 3 weeks, I have ZERO things to complain about, or dog hair to pick off (that wouldn't have been there otherwise)... Hope that helps!!
