Hello, I hope someone will be able to help, Does anyone know what I should give selby when on holiday in Greece to prevent bites from Sandflies and also mossys, I understand they have the I think french heartworm there as well. Should I use a preventative or just treat him when we get home. All the vets says is use the Scalibor collar but I am not sure that that is enough. he was born on the 19th November so will be just over 6 months when we go at the end of May, we are going for a month. Any advice would be welcome. thanks
