[Help] Possibly adopting another dog off Craigslist and need advice.

First off, I'm sorry if I tagged this post wrong or if I'm posting in the wrong place. Let me know!I live in New England and for whatever reason, there seems to be a shortage of Pomeranians here. I adopted a little Pomeranian last year and he really could use a companion.My dad found one on Craigslist, a cute little black pom that seemed like a good fit. 5 years old, about 7 lbs, no health conditions, good with dogs. I emailed and the lady is asking for $500 of a rehoming fee. That seems really ridiculous to me, but I'm not sure- I've never tried to get an animal off CL before. Does anyone else have experience with rehoming fees or CL animals? I got the Pom I have now for $120 at an animal shelter. via /r/dogs http://ift.tt/2sksirF
