Even though I don't live in Philadelphia area any longer I thought I'd give this site a try since googling "dog training" is overwhelming with paid sites, and I don't know of any dog training message boards.
In any case, I found a year old, Redbone Coonhound in a 20,000 acre forest. I was on a 7 mile hike and he and I crossed paths a mile in and he then proceeded to follow me the remaining 6 miles back to my car (I did not pass another hiker the entire walk). He did not have collar, nor had he been microchipped. I've taken him to the vet already where he received all of his shots and I scheduled an appointment for him to be neutered next week.
As far as I can tell he was never trained to be on a leash and he is extremely nervous whenever I bring him inside my house. He tears at the furniture and paws at the window trying to get out even though I am there with him. When he is outside he is extremely affectionate, a bit skittish, but wants to take off and roam, much like he did in the forest. I fear that not only is he going to destroy my house, but that if I ever take him off the leash I will never see him again.
And to put this in perspective for you city dwellers, I am now living on a 200 acre farm and we are one of the smallest farms around. So being off leash is not a bad thing as long as I can train him not to leave the property. The vet suggested feeding him 3 small meals a day so he realizes this is home, but that is the only advice I've got so far. Oh, the vet also mentioned that the neutering would probably help with the roaming, but I also need help with getting him to remain calm indoors.
The dog is a chick magnet though. When I take him to town every woman I see wants to pet him, so I can live with his faults if necessary.
