My Family and I recently lost our Yorkie of Five years. He layed down for a nap and did not return to us

It's been a few months and my Kids are still so sad, I want to get them a Yorkie for Christmas however as we can afford to care for the dog we canot afford an enormious lump sum in the $1,000's it seems they are going for. Is there anyone looking for a good home for a little one that may only be looking for a small fee or does anyone have any ideas on where we can look. Thank you
