Not sure if I fully understood this but - hopefully I can help a bit
You can more than easily play this game without exploring. Lots of packs don't do any exploring; you can earn mush from breeding out wolves, selling wolves, offering art or writing, boarding wolves, PVP etc
A lot of these are very dependent. Breeding out wolves for money usually requires wolves of high talents, rare defects of chimi/viti, high rarity all common coats etc. Art and writing are very full markets but if you can find a method or area that works well for you, you can still have a full pack from that alone. Boarding wolves is far better for a member with a premium account.
PVP is another way for your wolves to get battle experience however is far slower than exploring. You can also pay people to train your wolves for you; although, if you aren't going to be exploring I'm not sure why you'd need Battle experience? Wolves only need battle experience to aid them in explore/PVP. Out of combat, BE doesn't have any effect on a wolf :)
Explorer maps aren't really necessary? If you're struggling with them in particular, other than posting an image of it and asking for users to point you in the right direction, you can always restart the level.
If you're struggling with exploring I'd suggest checking out

As for food, the only thing hunger would effect is your pack's happiness, which effects the rate at which your wolves recover health. If your wolves aren't exploring your wolves won't need to recover health
Otherwise, you can use the hot spring once a day, under Pack >> Food and Drinks, which feeds and fills thirst for all the wolves in your pack. Or you can head to Realm >> Marketplace and either buy food from other members under Barter >> Search, or you can head to Slim's Foodshack (food is more expensive here though)
More often than not you can head to Realm >> Games >> Hidden Falls, and once an hour you might be able to find some food there :)
