In instances where this does happen at random and not frequently, the dog will probably not have symptoms of heart disease. Yet, if the erratic beats occur in sequence this will cause weakness, collapse or sudden death.
Once this disease gets bad enough to cause noticeable symptoms, your Maltipoo dog may have:
Fainting – When blood is not pumped properly through the dog’s body, this can cause periods of time where the dog is not receiving enough blood flow and the dog can faint. The fainting will happen for a few seconds to a few minutes depending on how fast the dog’s heart corrects itself.
Coughing - Each instance varies. Nevertheless some Maltipoo dogs with cardiomyopathy will reach a point where the ventricles of the heart enlarge. This then causes the walls of the heart to become thin and the heart itself will lose its strength. Coughing may occur.
How do you know if your Maltipoo has cardiomyopathy (arrhythmia)? This is a part of why this health issue
can be so tricky. There are usually no symptoms during early stages. This is usually discovered during a routine vet visit. This is just 1 reason why an owner must always make sure to have their Maltipoo examined on a regular basis even if the puppy or dog seems to be very healthy. Adults should be seen once per year and seniors should be seen twice per year.
The heart arrhythmias are not always found by using a stethoscope. It all depends on the actual frequency of the abnormal heart rhythm. Typically, the cardiomyopathy will cause an extra heart beat or a skipped beat and it must happen without a corresponding pulse in order to be diagnosed as cardiomyopathy arrhythmia. If the frequency is just right, a veterinarian will be able to detect this during a normal checkup.
In most cases, your dog’s veterinarian will use 1 hand to hold the stethoscope and 1 hand is put on the dog’s hind leg to feel their pulse. Why on the hind leg? This area contains a large femoral artery which vets find one of the best areas to accurately feel the pulse.
When an Irregular Heart Beat is Found
If your Maltipoo’s veterinarian believes that your dog may have cardiomyopathy, the next step is to perform an ECG on the dog. The best method to assess a Maltipoo for arrhythmia is to use a 24-hour ECG. This way, it can detect any arrhythmia even if they happen very infrequently. For this reason, your dog will need to stay overnight.
