Do any of you give your dogs piriton? Reason I ask is Roo started last night scratching like hell at his tummy. It started about 20 minutes after we came home from a walk. He was arseing around in a filthy ditch so I think he could have picked something up there thats irritating him. Hes not made himself bleed but it has gotten rather red. I bathed him in cool water last night, just his tum and that seemed to work for about an hour, then he started again. We also checked both of them for fleas and theres nothing that I can see. No sign of flea dirt, and Harvey isnt itching. A friend suggested Piriton but I rang the vet and, surprise surprise, they wouldnt recommend it because they need to see the rash first so I got nowhere asking for a dosage! Whole point was to try this to see if it helped before having to take him in! Ive been googling and basically found that some give ½ a tablet, others a full one. Has anyone else ever given it to a westie sized dog (hes 8.5 kilos). .
