Thanks for the good advice.
I am going to put up posters in the area, and place an ad in the local classifieds. I am concerned that someone might just want him due to him possibly being a purebred. I am pretty sure he is not from this area, as I have gotten to know most of the dogs around here pretty well. But, to act in his best interest, I shall give it a good shot by advertising with specific questions. I am upset that a puppy would not be supervised well enough to just wander off...he is not a fast runner at all. I would have been out day and night if my Lab mix vanished.
In the meantime, I will give him some of the Nutrical, and keep an eye on him. He is now seeming more alert and awake, but still drowsing off an on in his bed.
Keep the good insights and advice coming. I will need it in the coming days, whether he is reclaimed or stays here.
Can I just go to my vet and have him checked for a microchip, or do I need to go to a special place?
