I have just spent a lot of money purchasing a pedigree collie from Wales in the UK, and a lot of money getting him sent over to Jersey Channel Islands via plane. As soon as he arrived i noticed that he was very itchy and uncomfortable. I left him until the morning as he was a bit stressed from the flight. The next day he was even worse, he was constantly chewing himself and crying, itching like crazy. I took him to the vets straight away, even though he had a vet check the day before he flew. The vet informed me that he had a very bad skin condition which was obviously visable as he was covered in red lumps, a rash and flakes of skin all over. I spent a fortune at the vets just to get him looked at and have some puppy shampoo to soothe his skin. This puppy is only 12weeks old and is in a mess! As you can imagine, i am not a happy owner!.. I got on the phone straight away to the breeder to make sure he was aware of this problem, and asked him if he had not noticed the skin condition before he sent him to me, especially since he had a vet certificate from the vet saying he was ‘Fit to fly’. The breeder informed me that he had given the dog ‘Hartz flea drops’ the morning before he got on the plane. I had never even heard of this brand before, having worked in a pet shop for over 5years and knowing the best brands to use! I thought this was obviously a cheap make so no expense to the breeder. I looked it up and guess what?.. bad reviews and more similar stories from people who unknowingly administered this product on their poor pet! I am so annoyed and angry that this product is being sold. I will be warning everyone in the future of this product if it is not ceased off the shelves.
