Just wondered if it would be safe to give Harvey another worming tablet (he had a Milbemax on 1st Oct). He is scooting a bit and keeps trying to reach his back end. He's had his anal glands emptied (the vet said they weren't really that full). We are going away for a week and leaving him with a dog minder, so want him to be comfortable. However, if its not worms I don't want to give him unneccessary medication.
