comb the dogs hair well then bang the comb on a hard surface.... get a paper towel and damp it with water then wipe the surface where you banged the comb if the paper towel had red specks on it the dog will have fleas. The red is ofcourse blood.. from flea poo and scabs from itching and being bitten.
If you wish to go to the vets thats fine but [email protected] sell the same stuff alot cheaper than my vets... you will need to know the dogs body weight though.
When I found a crawly thing on my cat we gave them some tablets that get rid of fleas, then we but frontline spot on on them and then we set off a flea bomb in the house to kill any other fleas, then we had no problem since
Frontline we get it off a pet pharmacy website they are brilliant fast delievery cheaper than the vets aswell. Frontline we have used for years and never seen a flea on them. If you have fleas on your pet you are going to need to get one also to treat the home.
