Heart Defect (Congenital) in Dogs




The dog may be given oxygen therapy, nitrates, and cage rest. When your pet has regained stability, it will be scheduled for surgery as soon as possible. It is safe to perform this operation on puppies as young as seven to eight weeks of age, but pets with right to left shunting PDA should never have surgical correction.


Living and Management


Dogs with a normal left to right PDA shunt can be treated normally after they have been allowed two weeks to recover from their surgical correction.




Because this trait is genetically transmitted, dogs that have had a PDA should not be bred. The best way to avoid this is to have your pet spayed or neutered, and to make sure that you know your dog's hereditary history.
