We have a new pup in the neighborhood! Our next door neighbors adopted a pup off the reservation near by. The then 12 week old yellow pup was half starved and left tied to a post in the cold and sun without water. The owner was delighted to take $5 and hand over the rope to my neighbor. At first he looked like all the other scruffy yella dogs that have inbred for so long in the area. But as he was fed and cared for he has been the original ugly duck turned into a swan. This morning when I walked by his yard and he came out to say hello, (from a distance, he is still a little intimidated by my 3 older dogs), I saw that his floppy ears are now completely erect. He is a rich fawn colored dog with an impressive black mask. His eyes are large and he has a friendly intelligent air about him. I guess he is about 5 months old now and around 40 - 45 #'s. He may be one of the prettiest dogs I've ever seen. My best guess is that he is a Belgian Malinois or at least very close. My neighbors are nice, nice folks but this is their first dog. I sure don't want to interfere or cause any conflict as so far the pup seems great. But will my dogs be in danger from a working dog like this if he is not trained? Can the Malinois just grow up "right" on their own? My dogs never go out without me and are not allowed to leave our yard. But the two houses are inside a fenced compound of about 5 acres. Would it be better to "introduce" the dogs as playmates, or continue to respect the boundaries and hope the new kid does the same? So far the pup has made no attempt to cross into our yard to "join in" with my boys. But I know that could change as he matures. How would you approach this, or just let it go? I know I am a terrible worry wart and am trying not to "over think" this one.
