Question: Looking for bag for ER evacuation purposes as well.  Will this hold 3-7 days worth food & water for my pet with extra room for other necessities?
Document: I have had this for about four months and it's still as good as new. My dog weighs 60lbs so I got the medium and it fits her well. After a day of hiking my dog still seems comfortable in it so I assume, since no one really knows what goes on in a dog's mind, that it is in fact comfortable. The pack can hold about three days worth of food and a travel bowl.
I bought one to make sure that it fits both my 65 pound Wiemarimar and my 50 pound mix. Fits both. Nice sized compartments. Since we purchased the backpack to create &#34;in case of emergency&#34; bags for the boys, we were concerned that any backpack would be insufficient to hold 72 hours worth of supplies. They will be able to haul a portion of their water and all of their food.
My dog has pretty much ripped every strap off at one point and I have had to re-sew it with a speedy awl. The pack itself is large enough to hold enough for daytrips and overnighters. Summers I put icepacks in there to keep him cool on hot summer days . fall hikes food water and my contact info. SO in short if you like the pack be prepared to re-sew strap connections.
So far so good. It's held up great. The pouches have plenty of room to hold stuff. I could put at least 3 water bottle in each side. I use it on both of my dogs. One is a 45lbs and the other is 100lbs and the adjustable straps make that very workable. I love this!
I have a extremely hyper black GSD - 2yr old.. he hates it and I love this.. I make him wear this when we go for a walk.. really important to expend his &#34;puppy&#34; energy and this bag works to do that- when filled with 3 large cans of dog food. the bag however had some damage (cuts etc) when my dog brushed against a wall while getting out of the door. well made otherwise. tires him out.
You want to try to keep the weight evenly distributed so as not to strain your pal's muscles; but it can hold a lot!! He carried his food, treats, water, bug spray, and even some of our stuff!! (A small tackle box and another water) with room to spare!! It secures fantastically and fits perfectly. He still runs through bushes, jumps over fallen trees and branches and maneuvers through small  streams as if it weren't even there.
I have a 40lb blue heeler and wasn't sure if I needed a small or medium. This small fit perfectly. Plenty of room for some collapsible food and water bowls, some food and treats, and some other small items so your furry friends will be able to carry their weight on hikes. Handle on top is heavily stitched and seems like it would hold up if you needed to use it to rescue your critter from some water hazard or just help lift them over some deadfall. Would definitely buy again.
I bought this for my great pyr and he loves it! He is about 135 lbs and it fits him really well. Now when we go on camping trips he can carry his own food and water plus I strap a blanket into the bungee cords on the top so he has something to sleep on. Saves me from having to carry a ton of extra weight while backpacking and he barely notices it.
It still runs a little large, on a medium 40lb dog. But beyond a doubt, the durability and strength of this pack comes from it's great, durable fabric. The fleece lining led to no rubbing or chafing on the dog and could easily be used to pack 3-4 days of food for your dog.
We purchased this pack for our 3 year old 75 lb. collie/shepard mix. We were looking for an orange, reflective pack for visibility purposes; however, after reading the reviews for other packs we opted for durability over color. GREAT CHOICE!If you just want to tire your dog out on leisurely path or road walk, go with any pack you want. But if you take your dog out in the woods, up mountains, and bushwacking- this pack is the way to go!
