Vet Q & A
Why did my vet prescribe heart/breathing meds before dog tests?
We often treat a pet symptomatically before test results are available to us. I can only assume that your vet had enough evidence to suggest that Dee was hypertensive, warranting the use of Sildanefil, and also had signs of bronchospasms or breathing difficulty, warranting the use of Theophylline. I am unsure of your pets clinical signs to confirm this, but this would be a logical explanation. But ultimately if you want to 100% know why these medications were prescribed then it would not be considered rude or unheard of to ask your vet their logic behind this decision. It is always best to hear the information from the source rather than speculation from an outside source.

My dog has tachycardia, faints. VF/VT? Fortekor or beta-blocker?
Ventricular fibrillation is the heart issue that you see people on tv getting shocked to try to correct. If not corrected, it results in death within minutes. Ventricular tachycardia and atrial tachycardia are very serious problems. In some dogs it is only transient (meaning only lasting for a few seconds) or it can be chronic. If chronic, it often needs medications to convert back to a normal rhythm or at least decrease the heartrate. In humans, both of these conditions are treated with beta blockers to decrease the heartrate or in the hospital for IV medications and symptomatic treatment. Heart disease that causes these conditions has a poor prognosis for good quality of life for an extended period. There is the possibility that the heart rate is simply high and without an actual arrhythmia. This is common in dogs with heart failure that do not have enough function to pump blood throughout the body. I would need to see the ECG to tell. Through the rest of the weekend, try to limit Bono's activity to keep his blood pressure lower and decrease the strain on his heart. If he will respond to the fortekor, it may take several days. If he is continuing to faint, be listless, not eating, etc. he needs to be re-evaluated by a vet sooner than Monday. He may need additional medications to help with his heart. The use of beta blockers just depends on the actual heart issue going on; they aren't used for every type of tachycardia.

My small dog ate Vetmedin. Is this heart medication safe for her?
Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Harper. The dose she ate is actually below what the recommended dose would be for a dog her weight, so there is no risk of overdose. This single, low dose should not be a problem. Just don't let her get any more. I hope this helps!

My cat has HCM. What are the best treatment options for her heart?
It appears that nebivolol is being researched for many different possible uses in many lab animal species, but I could not find any information on its use in cats. From the information I could find, most vets have mixed feelings on using atenolol in cats with HCM. There does seem to be a consensus among specialists that it could help in cats with HCM that have Systolic Anterior Motion (SAM) of the mitral valve (seen on echo), but there are no studies showing a positive benefit.

Can Petco help me find accurate medication dosages for my dog?
Unfortunately, we are not permitted to give out drug dosages without a veterinarian - client - pet relationship. If you are seeking this information, I would obtain it through a veterinarian in person or through a veterinary formulary such as Plumb's or Merck. Hope this makes sense.
