Plain-English summary
A family of Chihuahuas had four puppies diagnosed with a heart condition called patent ductus arteriosus (PDA), which is a congenital issue where a blood vessel fails to close properly after birth. Three of the female puppies had a milder form of PDA and one underwent successful surgery to correct it, while the other two did not receive treatment. Unfortunately, the male puppy had a more severe form of PDA and had to be euthanized. This condition appears to be hereditary, as the mother and the father dogs did not show any signs of the problem.

Abstract
This report describes a patent ductus arteriosus (PDA) in four puppies from the same family of Chihuahuas, bred from the same mother and from two different litters. Identification of this congenital anomaly relies on clinical examination, radiography and ultrasonography. Three of these puppies were female, and had a type-1 PDA. A conventional surgical ligation was performed on one of them, whilst the others underwent no treatment. One puppy was male, and presented with a type-4 PDA, requiring euthanasia. Post-mortem examination and histopathological examination of the PDA allowed characterisation of the histological anomalies, which were identical to those described in other breeds. The mother and the two stud dogs were not affected. Even though the mode of transmission has not been fully identified, it is evident that this PDA is hereditary in nature. To the authors' knowledge this is the first description of this congenital cardiopathy in a family of this breed, and in a significant number of first-generation individuals.
