How can you tell if a newborn puppy is having breathing problems?

Hi, In most animals who have breathing problems you may notice: * Wheezing similar to Asthma * Breathlessness such as gasping or panting for breathe * Panting excessively after exercise or after running up/down the stairs * Laying down and taking deep breathes similar to panting and possibly accompanied with a fast heart beat. * Hacking/nasty cough after exercise. If you notice any of the above, then you must see your Vet. A lot of breathing problems in puppies are harmless and usually due to a build up on catarrh or a chest infection. But as your dog is a puppy, his/her immune system will be a lot weaker than adult dogs and because of this a minor infection or viral infection can become severe and take its toll on your puppy. Normal colour of dogs GUMS are pink or a light pinkish colour. You can see your dogs Gums by lifting up the side of his mouth by his teeth, and looking above the teeth. If this is ever any other colour beside pink, such as blue, purple, yellow or a grey/white then contact your Vetinarian immediately. The above symptoms I mentioned are obvious symptoms and not all dogs show obvious symptoms unless something is seriously wrong or when they require immediate Vetinarian attention. If you have a gut instinct that something is not right with your puppy then please take him to your Vet for a thorough check over.
