Hey Michael I am interested in getting this pack for my 11 month old female black lab (pure breed) She weighs 75lbs. right now and will probably grow a little more??? which size do you recommend? I see Roxy could be comparable in size.

Hey Trekker81 Roxy is actually the runt of her litter so she is pretty small. She is only 50lbs and she is not very tall. The top of her head comes up about an inch or two above my knee cap. I got her a size Medium and it fits her everywhere except on the front chest strap. Other than that this bag is great. If you follow the sizing chart for this pack and measure in the correct spot around your dogs chest then it should give you an accurate basis to pick your size.
