Where to get a real breed Beagle in Chiangmai

I adopted 2.5 years old Beagle since July 15 this year. Everyone in Mooban told me that her owner did not care about her at all. Noone ever looked for her.

I came back to Chiangmai on Saturday after spent 10days in Bangkok for my Kim's funeral ceremony. This evening I walked my dog and two young men and a kid rode motorcycle passed by. They asked me where did I get my dog as I look like theirs.

After few talking for awhile, we can tell that she is theirs. I gave her back to them. Even I wonder where they have been as everyone in Mooban know this dog? Why they did not look for her at the first place?

I spent more than 7,000B for the vet. I told them to help me for the bill asking for only B3,000. I gave them a vaccination record so that they have no need to do it all over again.

I want to have a clean cut even they offer me to visit a dog. I want to move on. Could anyone suggest me where can I get a pure breed Beagle?

Thank you
