So my Border terrier is 14 weeks old now (amazingly) and doing well - ok she's actually a handful but that's another thread
Last week DH saw little, very wriggly white worms in her poo. She was due at the vet in the next couple of days so we phoned to check - fine, said the vet, just keep your appointment, no need to bring her in earlier.
So over the next 2 days there were worms everywhere - spontaneously coming out .
Industrial strength wormer prescribed, one a week for a month, then she's to move onto her regular programme plus. It's all fine now, no worms seen since the first dose.
But I was totally shocked - she has been wormed at all the proper times so far, so I thought that would prevent it. My eyes have been opened. I have a lot to learn...
