so now that my baboes are outside running they are also eating EVERYTHING!!! chewing sticks, pine cones, grass, dandelions, dirt, tree bark and lick sap on a old stump... now i know sticks can be dangerous so i let them lick and chew until they actually start to knaw off pieces... but what about grass, DIRT, pine cones, etc... is this just what dogs do?

the puggle i am house sitting for does the same thing with them... she actually got into dirt when i was looking and drank alot of water... then ran an out it came (throw up)... she was fine and started to run again... i am sure taht was a coombo of too much water, dirt and running....

its hard with 2 (3) dogs to keep up on a 1/2 acre expecially with there speed!!! 1 will listen to drop it but the other hasnt learned it yet.

any insight as to teh do's and don't of outside activity / eating would be great!
