It's quite possible . Same reason why dogs/cats eat grass - it soothes their tummy/digestive tract, makes them vomit hairballs etc.

That basically is activated charcoal then, the firewood being burned brings it to a high enough temperature to oxidize it:

Activated carbon (aka activated charcoal) is carbon produced from carbonaceous source materials like nutshells, peat, wood, coir, lignite, coal and petroleum pitch. It can be produced by one of the following processes:

Carbonization: Material with carbon content is pyrolyzed at temperatures in the range 600900 C, in absence of oxygen (usually in inert atmosphere with gases like argon or nitrogen)
Activation/Oxidation: Raw material or carbonized material is exposed to oxidizing atmospheres (carbon dioxide, oxygen, or steam) at temperatures above 250 C, usually in the temperature range of 6001200 C.
Of course some dogs just like to chew wood/sticks so maybe they both just like the taste
