Have you tried the baofeng walkie talkie? Might be a good item to utilize out there. I tell my kids to be weary of dogs, you just never know. 

 Actually we have walkies, just cheap walmart ones, but we dont usually carry them with us.  Need to change that. 

 Yeah the Baofeng ones on Amazon are g2g. I just use around the house or the kids will mess with them.
