An aortic thromboembolism in cats or dogs refers to a blood clot in your pet's aorta. The condition is most commonly characterized by a change in your pet's voice, which may become higher or lower -- or your pet may not be able to make any sound at all when attempting to speak. Pets with an aortic thromboembolism may also exhibit distressed breathing, or an inability to move properly or at all. If you suspect that your pet may be suffering from an aortic thromboembolism, you should consider this an emergency and seek veterinary help immediately, as the condition can be fatal if left untreated.
