But then they do say we now see lot more immune related illnesses than in the past...
and probably do stick so may more chemicals in our doga than they used to.
Just a thought...
I have never heard that 3 week rule before, actually I believe with our last puppy we were told to worm her before her first vaccination at 12 weeks...
Edited to say I would not want to use flea treatment on a young puppy like that anyway, do people use them on little puppies??
My girl is now a year old and has never had a treatment for fleas put on her or had fleas!
But then she is not in UK yet so maybe I will change my ways here if there are more fleas around...
She also mixes with dogs everyday so it is not because she has no contact with other animals.
