We have 2 female Mini Schnauzer's both 6 years old (both spayed) who we have had since puppies, they get along very well and are very much loved pets.
We have been contacted by a local resident who has a 14 week old puppy, after just 6 weeks he has decided it is not working out and wants to rehome the puppy.  He would like the puppy to go to a pet loving family (he has seen us out and about with our dogs) and asked if we would consider taking it.
It is a toy breed male. 
Can anyone advise me how my two older girls would react to bringing a male puppy into the family.
It is really pulling at my heart strings to take the puppy and give it a good home, just worried about how my two girls will be.

Girls will probably take to a male better than another female. Try meeting up on neutral ground and see how they react and take it from there.

Have you encouraged the OP to return the puppy to the breeder?

I don't know the man really, I have passed him in the street etc and said hello and that's about it.
I have just called to the house to suggest he call the breeder he purchased the dog from, he brought the puppy to the door step for me to look at, it is a cross breed, he seems to think yorkshire terrier/bichon frisse :(, he did not give much away about where he got it from, just said through a friend.
So sad that ignorant people are breeding dogs to make a fast buck.
I will say in the defence of the current owner, the puppy did seem healthy and alert.

In your situation I would do it - particularly as if things don't work out, this is the sort of dog who will be easily rehomed - unfortunately they are so easily rehomed the wrong people can easily get hold of them, which is why I'd take it in.

I agree, I'd be inclined to take the pup in, if all goes well, great, if not, then should be reasonably easy to re-home.

I would not take the pup on, had this many times with friends over the years and like yourself from fellow dog walkers who have bought on impulse, I always say NO!

If we all gave in to puppy eyes we'd all have 20+ dogs, be strong! There are thousands in rescue just the same, it's not your issue or problem.

If you had no intention of another dog, if you would not have chosen this cross, if you are happy with what you have, just say no, please, let the pup go back to the breeder to deal with, don't allow yourself to feel guilty, it is for the owner and breeder to feel guilty alone, not you or anyone else he tries to palm the pup off on. 

You may well eventually want another dog, you may not, you have two and the status quo is right, if you eventually get another dog it should be because you planned and wanted one, you chose the breeder, you chose the breed or cross, you have made sure it is coming from a reputable source so as not to encourage BYB's and Puppy farmers, and it should have all breed related health tests.

I say don't be sucked in.............. walk away and enjoy the two dogs you chose who you are happy with.

How about give him the details of a someone like little dog rescue  who foster their rescues until a home is found. carrington is right but I would struggle with this maybe foster for the rescue some will rehome straight from the dogs home

Thanks all, my heart is saying take him, my husband is in absolute agreeance with Carrington, we are not a dog orphanage and cannot be resonsible for clueless breeders and those who have taken ownership of a puppy without looking into it properly
As much as we are dog lovers we had no plans to take a third dog, just can't help feeling sorry for the poor pup, would hate to think it is going to get passed on again to another home that does not really want him.
I have called a couple of dog charities today, one of them can possibly get him a foster home next week, going to speak to the current owner and give him the details.
Will keep you posted over the weekend.

I would take him in but let the original owner know that if he doesn't work out for whatever reason you will find a nice home for him yourselves.

Our groomers were in a similar situation , a lady came in and wanted  ( rid ) so she said of her new chi x pup , as the ONE she ordered did not look like the one they sent !!!!! INTERNET ORDERING :(
They are really soft and felt for the pup and bought it off her so that it got a good home .
The woman went in a couple of days later and said " Look at my new pup , this is the the one I wanted , it's the right colour see !! , they got it right this time "
I couldn't believe anyone could be like this . I wonder what would of happened to the poor pup if they hadn't taken it on , but doing so only gave her the cash to go do it over again , and line a puppy farmers pocket !
To say I am mad is an understatement.

If it were me and I felt like I needed to take him then I would , but would have to educate him not to take any more pups or dogs on a whim.

If the man had approached me to take his pup on, I would not pay him for it as I had not offered to buy it.
