Wanted: Looking For a Yorkshire Terrier UNDER 8 Months! in Brampton, Ontario

Hi I am looking for a small Yorkshire terrier that is under 4 months, 8 months at the max. Preferably I'm looking for an 8-12 week puppy, but that is too early to get neutered/spayed. I am looking for a puppy that will do good with other dogs like my shorkie who is a neutered male dog, 14 pounds/6kg. My dog needs a friend after his old buddy passed away. I am looking for a yorkie who will weigh no more than 3kg, 4 at the max. No mixes please, unless she/he will 100% guranteed to be under 3-4kg. I prefer a male puppy. If he's a male, thats better! :)
I will pay no more than $230-$300 if she/he is vaccinated at least once, de wormed at least once, good with other dogs, and started potty training on newspaper or training pads.
The maximum I will pay will be $450-$510 if the puppy is neutered/spayed, vaccinated at least once, de-wormed at least once, good with other dogs, and started potty training on newspaper or training pads. If she/he is microchipped, that's better! But she/he doesn't have to be microchipped.
Must be located in Brampton/Mississauga area!!!
