We also use CSJ Billy No Mates, you can get it direct from the CSJ website or you may have a local stockist... A £12.50 pot is over half full still with our boys having started this pot about 10 weeks ago
Our boy really doesn't like the flea treatment going on. I did wonder if it was because it irritated his skin but couldn't rule out him just not liking the process fullstop.
We feed a Dorwest Herb garlic tablet once a day and have had no fleas in 3 years. We've had a tick, but they are easy to remove and I was told by my vet we don't get dodgy diseases from ticks in the UK.
