Thanks. Yeah, he had me scratching my head a number of times - seemed like an odd approach that gave short term, but possibly not long term results.
I don’t have any specific problems with my dogs - I’m just interested as I live in Thailand and am forever taking in strays or at least trying to help them out when practical so the more knowledge I have, the better.
I’ll PM you if anything comes up, though.
You are a hero. I donated to Soi last year monthly.
