Thank you for posting the link to the Academy of Veterinary Homeopathy. For some reason the link was not active in your post, so I am posting it again for you. http://theavh.org.
Also, good luck with your dog's progress. I am so glad to hear that things may be improving for him. Please keep us updated on the progress you make with him. Your experience is helpful to all of us.
I've recently started working with my homeopath too. Although my dog is asymptomatic for heart disease, he has other health issues, and after doing a full work-up on him, she's chosen a remedy which we think is his constitutional remedy. My hope is that this will strengthen my dog's overall health even further, including his heart/valves.
I was giving my dog 4 tabs of Cardio-Plus a day (2 with each meal), not 4 tabs twice a day. Now he's only getting 2 tabs a day (1 with each meal), along with 1 tab of Cataplex E-2 a day. We will monitor him to see if this is enough heart support for him. If we feel he needs more, we will just add back some of his supplements, but my vet feels that might not be necessary.
If it were me, I would give Cutie at least 1/2 tab twice a day, maybe even 1 tab twice a day of Cardio-Plus. It can't hurt and it can only help. It is food for the heart and it does contain natural CoQ10 too. If you increase the Cardio-Plus, you should probably let your vet know so she can make adjustments to the other herbs, if that's necessary. There may be a synergy in the dosages she recommended.
Here are just a few things to keep in mind for anyone who has a dog with a murmur.
1. Once a murmur is detected, an echo should be done once a year thereafter to monitor it. Low cost echos can be done by a board certified cardiologist at a Cavalier health clinic. Most breeds are accepted at these clinics. To locate one go to: http://www.cavalierhealth.org/health_clinics.htm. Note: These clinics are good only if your dog is not seriously ill and only if you're doing this just to monitor them. If your dog is sick and needs medical attention you will need to find your own cardiologist, because they cannot treat your animal or prescribe meds.
2. Learn as much as you can about your dog's condition and what your options are for treating him. Monitor him closely for any changes. Don't let doctor's scare you with comments like "nothing can be done" or "it's inherited and there's no treatment." I don't believe that that is true. Doctors are limited in their knowledge too. As long as our dogs are alive and breathing, they have a chance to get better.
3. If a protocol is not working for your dog, consider trying something else?or even a different vet. Don't be afraid to combine therapies, such as nutritional or herbal with maybe homeopathy, or even acupuncture. If using homeopathy, don't attempt it yourself and seek out a trained professional through the link provided above. Consider acupuncture. Although I don't know much about it for congestive heart failure or heart problems in general, there is info written about it on the internet. I think it is worth looking into as possible option.
4. Learn what the normal resting heart rate should be for your dog and how to monitor it. It is different for small and large dogs. Note: I have read that a 10 bpm increase in heart rate increased the hazard of progression of heart failure by 22%. Additional Note: Four years ago my dog's resting heart rate was 128 bpm and he had high blood pressure. Then I started his supplements and at his next echo one year later, his resting heart rate dropped to 108 bpm, despite the fact that his weight was still pretty much the same. Since that time, each subsequent echo has measured his heart rate at or about 100 bpm, which the cardio said is nice and relaxed. The cardiologist also mentioned that he has a good sinus rhythm, which means, I think, that he has a good steady heart rate with no arrhythmias. Although we haven't checked for the high blood pressure with the cuff, I think it disappeared when his heart rate normalized.
