Hope he's ok...and you I got some of that in my eye once( don't ask) OMG,it hurt so bad

If your vet says you can give him Piriton, you want the regular and not the non-drowsy version.

You can buy the generic form of Piriton from chemists as Chlorphenamine Maleate as it is much cheaper, but do not tell them it is for a dog as pharmacists will not sell it to you - I believe it is illegal for them to sell human medication for an animal without a prescription from a vet.

I hope poor little Winston is OK and that your cold and cough go quickly.

Okay...turns out it wasn't the vapour rub.
Winston has been on steroids for almost a year now , so he can get infections really easily. He has a small pug acne spot on his nose and the infection from that has travelled up and caused the swelling. So yet more antibiotics for my little guy.
