We recommend that you worm your pup monthly until they are 6 months old then every 3months after that for routine worm control.
HOWEVER we are in a high lungworm incidence area. Lungworm is spread by slugs and snails which your puppy can swallow when playing with them or even when eating grass. Therefore we recommend using a monthly treatment that protects against lungworm as well as routine worms. Many of the standard wormers are not effective against lungworm.
Lungworm can cause lung problems, but also can affect the brain, causing fits and other neurological problems, and also affect blood clotting.
Tapeworms are not such a big problem in this area. Dogs become infected by eating raw meat or by ingesting fleas so they are more likely to be seen in dogs that hunt, eat raw food, or have fleas. Tape worms are more of a risk in other areas so if you travel abroad or to Wales or Scotland with your dog you should treat for tapeworms.
