We were pulling dogs north from California shelters (to Wa State) to the tune of 40-60/month for about 4 years and they had to be healthy, pass a vet exam, heartworm testing neg..some were euthed because of not passing the testing required.
Additionally we moved five from Wa state to Michigan a few years ago and that was expensive and rigorous as well. Including individual crate inspections at the airports, on top of veterinary certificates of health and proof of all vaccines.
So my experience doesn't match to your links.
Both TBDs and heartworm are curable.
Why were they rejected, anyway?
My dog forums are full of alerts to scammers.
What may have started as a noble cause has naturally attracted scumbags looking for a quick buck.
As a related aside-from, Burt Ward [Robin, the boy wonder] is universally loathed by the dog community because he started up a “rescue” which is really just dog-flipping scam.
To make it worse than that, his “adoptees” must only be fed “his” dog food brand, which is obscenely over-priced.
There are always maggots in every barrel of apples.
Our local ‘real’ shelter has not that many dogs to adopt, most of them pit mixes, because private rescues are rampant, here.
A lot of them are run by wonderful people who literally pay out of their own pockets and care only that the animals get good homes.
The rest are owned by dog flippers and crazy people.
You *rarely* find a purebred anything because the breed rescues grab them up, first.
And then they charge obscene “adoption” prices for them.
[$600 and up]
Bizarrely, that’s part of why we have so many pit-type dogs in the area.
No purebreed rescue wants them and normal people can’t afford the breed rescue prices.
