Not that season! Flea and tick season. The more people I talk to about this the more surprised I am how few people use preventative measures; or worse, understand what prevention is all about.
When talking to potential adopters I always tell them what sort of flea prevention the dog has had, when they had it & when they are due for another treatment.
Without fail, 9 out of 10 times they will say “Why? Does he have fleas?” Whether or not a dog has fleas is irrelevant when it comes to prevention. The trick lies in stopping them from getting fleas in the first place.
