We have a 13 yr old Cairn/West Highland White terrier mix (Josie) who has an enlarged heart. About 4 weeks ago she had a fainting spell, so in the last two weeks our vet has prescribed twice a day Enalapril maleate 2.5 mg., Furosedmide 12.5, and Vetmedin 5 mg. with the goal to get her down to one prescription a day.

She has a slight cough which he thinks is similar to kennel cough and has given her a prescription for Clavamox 1.5 ml twice a day and a cough tablet (guaifenesin-dextromethorphan). Her chest x-ray shows her lungs to be clear.

Could you tell us what the best diet is for her to be on, how much exercise she should be getting daily and also any supplements that would be good for her condition. Also can the supplements be purchased through a health food store or do they need to be obtained through a vet’s office?

Thank you for any information you can provide us.

Comments for Dog diet and supplements for enlarged heart

Oct 26, 2011My Online Vet Response for Dog Diet and supplements for enlarged heart
by: Dr. Carol Jean Tillman

Hello Josie’s Parents!
Heart conditions are not uncommon in older dogs. The prescriptions that your veterinarian has started for Josie are good. But with good nutrition and supplements, you may be able to wean her off of some of them.

A good book that I would highly recommend to guide you along, especially for diet recipes, is Dr Richard Pitcairn’s book, Complete Guide to Natural Health for Dogs and Cats.

He is a proponent of raw diets, with NO added salt, since raw meat is superior to cooked for better nutrition. See our page on the 10 best dog food options for a list of some raw food diets. Also offer Spring Water or other filtered water for her to drink.

If she is overweight, she should be on a weight reduction diet, since that will be easier on her heart. As Dr. Pitcairn says, “Because more heart energy is required to push blood through all that fat!”

Supplements that provide a good source of B-vitamins and minerals are important for heart tissue. A good supplement would be OrthoMolecular Specialties, Mega C Powder.

Josie also needs Vetri-Science Coenzyme Q10 (10 mg), give her 10 mg in her food two times daily.

Here is the rest of my response…

Standard Process products such as Canine Cardiac support would be excellent for Josie.

Regular daily exercise that is not too strenuous or exciting would also be good for her, such as taking her for a walk, for about 10- 15 minutes twice a day. Monitor her for how tired she is, and do not overdo it (Avoid hills/steep driveways, lots of stairs

Avoid cigarette smoke.

There are numerous homeopathic remedies that are useful for heart conditions, but it would be best to seek the help of a holistic veterinarian to guide you in which ones to choose.

Another resource for vets knowledgeable in homeopathy is AVH.org.
