Disease is easily prevented by regular worming
Dog owners are being reminded about the importance of regularly worming their pets against both round and tapeworms.
Dogs which have not been treated against worms can suffer weight loss and sickness. They can also contribute to the spread of diseases such as hydatid disease and eye disease - both of which are potentially dangerous for humans, but are extremely rare in the UK.
The reminder was made by the chief veterinary officer for Wales, Professor Christianne Glossop.
Prof. Glossop said: "Even if your dog looks healthy, it could still have worms so it is important to get into a regular worming routine. This routine should be advised by your vet and based on your pet's lifestyle. However, as a general rule, puppies should be wormed agains roundworms and dogs should be wormed against roundworms and tapeworms.
"Disease is easily prevented by regular worming and is an important element of responsible dog ownership."
Dog owners are also being reminded that if they are bringing their dogs into the UK, then they must be treated against tapeworm as part of the Pet Travel Scheme.
Prof. Glossop explained: "Some worms are more likely to be picked up by dogs while overseas. If you have taken your dog abroad this year, it is particularly important to worm them and follow the requirements set out in the Pet Travel Scheme.
"The treatment must be administered 24 to 120 hours before entering the UK and recorded in the Pet Passport. Mandatory tapeworm treatment is not required for dogs travelling from the Republic of Ireland, Finland, Malta or Norway."
