Do not buy from this company, Their service and customer service is absolutely appalling. I ordered Nexgard Spectra - 2 prescriptions for 2 different sized dogs. As I had previously ordered from another company - there was a small error with the weight of one dog on the prescription - but had cancelled that order as I could not get hold of the company by phone - and reordered from Petdrugsonline. I had a very curt and insulting email from Petdrugsonline saying that I had issued multiple orders and therefore misused the prescripition and that they were going to "pass on evidence of prescription misuse to our regulatory authority, the Veterinary Medicines ". They did not bother to contact me to find out the reason for ordering from them. They do not answer the phone, even though I have tried to contact them. To date, I have had no reply to an email. Do not use this company. I have realised that practically all of their reviews are one or two stars. This says it all. In a day and age when so many companies are striving for business, it seems to me that Petdrugsonline do not need the business and do not care about any potential customers.
