Help with worming and fleaing

Hi everyone Harley is 12 wks now and was last wormed and flead at 9 weeks by the vet , but over the last day or so he has gone off his food and scratching the bottom of his bum by his tail alot I was just wondering when he would next need another worm as I am unsure what to give him and how often.
Thank you

Hi Beth
Do you know if he had regular worm treatments before you got him?

Drontal Puppy suspension 50ml is an effective treatment in the control of gastrointestinal Roundworms in both their adult and immature forms. Effective also with mature Hookworms and Whipworms in dogs, all of which are present in the UK. Puppies should be treated at 2 weeks of age and every 2 weeks until 12 weeks of age. Thereafter treating in 3 monthly intervals throughout their lifetime.

Dosages:

1ml Drontal Puppy suspension per 1kg of bodyweight

Check with your vet first tho

Thanks for the help yes he was wormed at 2 week intervals 3, 5, 7, 9 so was just wondering if I should carry on at every 2 weeks or every few months

Three months after 12 weeks hun

If you are not sure just call the vet but peppa was chewing her tail base a while ago and she never had a worm in her life.

Mia does this all the time
