While panting immediately after birth is a completely normal occurrence, prolonged panting is not. If this issue continues for several days after delivering puppies, your dog may be experiencing problems such as: an incomplete birth, milk fever, a high temperature, heart problems, or pain of some sort.
Incomplete Birth
If panting continues for a few hours after birth, it may be due to an unborn puppy or the late delivery of a placenta. Regardless of which it is, if you are inexperienced with puppy delivery, it would be best to contact your veterinarian for medical support. There are a few medications that can be given to help move the placenta along after it has been determined that there are no puppies remaining within the womb. Sometimes, a surgical procedure will be needed.
Milk Fever
Also known as eclampsia, puerperal tetany, and hypocalcemia this condition is caused by low blood calcium levels. One of the major symptoms is excessive panting, and while it may not seem serious at first, delaying treatment can result in death. Sometimes after giving birth, usually occurring within the first 4 weeks of delivery, a mother dog may have trouble maintaining healthy calcium levels as a lot of her own supply is passed through to the pups within her milk. This leaves the mother with a serious depletion of calcium and can result in milk fever, which will then need to be treated immediately by your veterinarian.
High Temperature
A high temperature is most always a sign of something more serious and should be checked out as soon as possible. After birth, regular temperature for the mother will be around 101.5 degrees Fahrenheit with a one-degree variation allowed. If it is any higher than this, severe panting will occur. This is an indication that something is severely amiss and you will want to receive medical attention for your pet immediately.
Heart Problems
Some more serious problems could appear after birthing due to the stress put upon the body. Examples of heart problems that can cause panting are heartworms and congestive heart failure. If you notice that your dog’s panting is paired with lethargy and coughing spells you will want to get her to the vet as soon as possible in order to be diagnosed.
Pain
If panting continues longer than a few days after birth, there may be some underlying issue that cannot be seen from the outside. Complications from birth can cause a lot of pain to a new mother, and can be quite common with a first pregnancy. Monitor your dog carefully and if the problems persist or worsen, seek medical attention as soon as possible. Most bitches who whelp normally will not require pain relief during or after labor.
