The dog has fleas! I can't imagine where from - he doesn't see other dogs and only occasionally comes across one on a walk.
He has a seresto collar which is only a month or so old and I've put spot on on him. Combing is producing perhaps 10 a day over the past 6 days. I'd say the fleas seems smaller and less jumpy now.
It's horrible. How do we get rid of them - do I need vet strength meds? What about the house?
In all my many years of dog ownership I've never encountered fleas!
Help. What do I do next?
