male lab appeared at our house and wont leave or stop howling

Question
QUESTION: Hi, I'm sorry to bother you with a seemingly silly query.

yesterday, an in-tact male chocolate labrador appeared outside our house. I met the same dog the previous day walking my two spayed female dogs, he followed us for a bit before following another dog. He did not see our house. I'm just intrigued as to why he came to our house, if my two dogs are spayed.

Secondly, much to my husband's annoyance (!), after the dog refused to go away, I let him into our gated driveway as I am going to take care of him whilst I attempt to find his owners. However, as I have no idea whether he is house trained and because he won't leave my poor golden retriever alone,I don't particularly want to keep him inside the house.

As my dogs sleep inside the house, we discovered last night that he howls as he can't get to them. Is there anything I can do to stop this?

It's such a shame people let their dogs roam around free to cause havoc without tags/chips. I don't want to turn the dog away but I also want a bit of piece and quiet!

Anyway, thanks for any advice, just hope I can find his owners as we really can't have another large dog in our house!

ANSWER: As long as he has no tags, I think the best thing is to call animal control.  They should have a scanner for chips, a secure place to keep him and contacts to find his owners.

QUESTION: The trouble is we live in Mexico City and they don't seem to have animal control. We took him to all the local vets to see if he had a chip or if any of them recognised him and no luck. We are in the process of putting posters up.

If we have no luck finding his owners, my in laws have a ranch outside the city with about 10 dogs...mostly spayed females, but there are 2 un-neutered males (a german shepard and a st. bernard) and one neutered male (a labrador). If we were to neuter this labrador and take him there, would it cause territory problems with the other male dogs, would they be likely to attack him? The two un-neutered males do have the occasional fight but as far as I know they leave the neutered lab alone.

I think he is fairly young, he seems to have teeth still to come, so if we were to neuter him and he calms down, I'm sure he'd make a lovely pet. Just not for us unfortunately.

I'm still hopeful we might find his owners, bt if not, the best place for him may be my in-law's ranch, so I would be interested to know whether this would be a viable option.

Thank you.  

Answer
When I get the questions, I am told the country.  Perhaps I need to be more observant.  I do get many questions from India and the Middle East.  I can only guess at what resources they may have available there.

I can't say how he would do with your inlaws.  Neutering will help.  Partly it is like mixing people.  Put 2 with an attitude together and trouble.  Others, the more the merrier.  

One more thing would be to check with neighborhood workers.  Where we live, we are at the edge of town and occasionally people dump dogs here.  For the 4 years our son was the paper boy, if he didn't recognize a dog, we figured it didn't live in the neighborhood.  So if you have anybody that know the neighborhood, talk to them.
