Fleas a crowd

Hello

Please can you recommend a natural treatment to protect my dog (and cats) from fleas and ticks? 

I don't like using spot on drops on them - my dog has a reaction to them and I think it may have caused my old cat to have nerve damage. Do you know of any alternative natural treatments that are effective?

I hope you can help. 

Thank you

The natural way

I make all my own dog food, biscuits and pellets and would be very grateful if anyone could advise me on what to use to de-worm and also keep my dogs safe from ticks and fleas naturally. My local vet does not have any advice and believes that natural remedies don't work. I would like to believe she is incorrect.
