A flea invasion
For a number of years I've used Seresto for my Australian Labradoodle but for some reason it doesn't work anymore. It's as if the fleas have become resistent to the product. I normally buy a new one every 6 to 7 months but as she kept on scratching, I bought her a new one last month. However, both my dog and my house are covered in fleas. No more Seresto for me.
