Nursing Maltese loses coat

Every time my female gives birth she begins to lose her coat especially around her neck. After she quits nursing the pups she starts growing it back. I have asked my vet and he says it is normal and nothing is going to stop it. Is this true?

• It's not unusual for long coated dogs to "blow" coat (loose it) after they have had puppies. Most generally do it after they wean them but some also have a fair amount of blow during nursing. The production of milk for the babies takes much of the nutrients the bitch is receiving and so little is left over for the coat. I find that makeing sure my girls are eating well, give them calcium supplements and some good vitamins help. Make sure the food they are eating is high in protein and fat during this time.
