Never let a child pull his ears or tail. The greatest danger to your dog is the garden. Use strong gates, latches and fencing, make sure that there are no gaps in hedges. Keep all chemicals locked in a garden shed and cover rubbish bins. Make sure a garden pond is kept covered.
Many garden plants are poisonous to dogs.
In particular, Westies should be prevented from eating all kinds of fungi kept away from laburnum trees and mistletoe berries. All Westies should have a routine annual veterinary examination. The puppy will need worming more regular at first. Choose your vet with the help of other pet guardians you know, but always enquire with other vets the cost. Find out your vets emergency facilities and keep the telephone number close to hand.
