Welcome to Trailspace culrlyshirley,
F klock is correct, your dogs pads require conditioning in order to be tough, similar to humans going barefoot, calluses will develop and the foot gets tougher with time.
I also have an Akita, a male named Boo. He goes with me on solo trips in more remote areas of the Southern Appalachians 3 or 4 times a year, and on day hikes close to home. Properly conditioned and trained these are impressive hiking companions, very smart and alert, not easily given to a lot of "tom foolery".
I would say that booties are not a necessity, but that does not mean they have no merit. On the contrary, booties are used to protect the dogs feet from a harsh surface such as snow or sharp rocks, and / or just the wear and tear of a long trek. If the dogs pads are getting cut on the scree, protection of some kind is in order I would think. Some people use wool socks instead of booties for dry rocky trails, but booties are the preferred choice for snow it seems.
I do not have much experience with my dog in snow, mostly on soil & rocky surfaces. I know others here on Trailspace recommend booties for trekking in snow to keep the snow from balling up between the pads among other reasons.
My current dog hates booties, we go into some pretty steep terrain and I think the booties cause him to loose a lot of traction and dexterity that he normally has without the booties. Barefooted he can dig in with his massive feet and nails.
Having said that, I have to pay close attention to the condition of his pads, especially in rocky terrain. I like to do a quick check every couple of hours when in rock than can be sharp This does not take but a few seconds and should not turn into a big ordeal if you start training your dog for a pad check beginning with short walks around your home.
It has been very useful for me to carry a small first aid kit I made up to deal with cuts and such. You also want to avoid letting the dogs pads stay too wet or too dry, both can cause problems. A light coating of Vaseline seems to help my dog with both problems. Just like as with our feet, proper care, catching problems early, and having first aid supplies on hand has been the best way I've found to keep my dogs feet healthy and in great shape.
Lots of info on the web about proper care and treatment of your dogs feet, plus which first aid supplies to pack and how to use them.
All in all, I would say whether or not you use booties on the dog will depend a lot on the environment you expect to encounter, the length of the trip, & how tough your dogs pads are. Quite honestly, I also took into consideration how happy my dog is with the decision as well, not from a training perspective, but how well he could navigate with or without them.
As far as your dog carrying a pack, I would avoid much weight in the pack until the dog has completely stopped growing, which can be upwards of 18 months for Akitas and other large breeds. A good rule of thumb is that a healthy dog can carry up to 1/3 their body weight. I prefer to keep it around 20 - 25% max.
Stressing the joints with a heavy pack during the growing period can cause problems in both the short and long term. I would work up to weight and distance slowly over a period of weeks to months after consulting with your VET and taking a professionals advise under consideration. Also maybe make it rewarding to your dog, have special treats just for when she wears the pack on hikes, works for me.
Dogs can be a lot of fun and a great companion, however, sadly a lot of dog owners do not manage their dogs very well and create a wide range of problems for other hikers. It is very important for us dog owners to go the extra mile and do whatever it takes in order to be considerate of other hikers on the trail, some of whom have had bad experiences with dogs on the trail. I keep my dog on leash unless in really remote areas. I personally will yield the trail to other groups, and have trained my dog to quietly sit still at my side while I say hello. For many people, seeing that your dog is well behaved & trained puts them at ease.
Hope that helps, tell Ursa I said HI! (Great name BTW)
