We are in the middle of winter. However, it has been a relatively mild one which fleas may well appreciate! Many people believe that fleas are dormant in winter but this is not the case. Central heating and a nice cosy home make it summer all year round for fleas so don't forget to continue using your usual preventative treatment on pets, whatever the time of year. Eradicating fleas from the dog is fairly easy but preventing re infestation due to the fleas living, and laying eggs in carpets and soft furnishings is a real challenge so it is well worth being diligent in preventive treatment.
Plenty of useful information on the control of parasites on It's a Jungle
website. Also consult your veterinary surgeon about a suitable regime for your pet.
