This lightweight sleeping bag will act as a perfect light dog bed after a day exploring the trails. When the temperatures drop, you can actually zip your pup up inside the bag to retain heat. The polyester fabric shell is stain resistant, quick drying, easy to clean, and, best of all, the whole thing packs small enough to fit on the outside of your pack. [$99; ruffwear.com]

It has been shown that out of all dog breeds, it is the Labrador Retriever that is most likely to be obese.[73] In a 2016 published study it was shown that out of 310 Labradors, most were missing all or parts of the POMC gene. This gene plays a part in appetite regulation as well as indication of the amount of one's stored fat. The study concluded that the absence of that gene had a significant impact on Labrador weight and appetite.[70][73] The POMC gene mutation is present in only one other breed – the Flat-Coated Retriever.[70]
