my 2 year old mastiff has not eatten yesterday or today, its not like him to miss his food,he eats around about 6/8lb of pet mince a day mixed in with mixer. he also has a bit of a cough ive booked him to see the vet but i was wondering if anyone know what it might be just to put my mind at rest till i see our vet

It could be possible that its kennel cough

he may have something in his throat does he chew wood or had a bone????
other than that I agree with paxojust make sure he is taking fluids.
