How much exercise is safe for my dog undergoing heartworm treatment?

Hello. For the most part, you want to institute a level of exercise reduction so as to decrease the strain on the heart. This should start on the day of diagnosis, & continue with even further reduced exercise when heartworm treatment is started. Once Julius has been properly treated for the heartworms, he can resume normal activity levels. Thank you.

I'm so sorry to hear that Buford has contracted heartworms. I adopted a dog with heartworms and it can be challenging to decide on the right treatment protocol for a high energy dog. First, let's clarify that at some point the adult worms are going to die. That can occur from us killing them with the medications that we call an "adulticide" or it can occur when the adult worms reach the end of their life expectancy. At that point. if Buford is exercising, the worm dying can results in a clot to the lungs. An adult worm can live up to 5 years, so you really should keep Buford exercise restricted until his heartworm disease has resolved regardless of how you treat it. Second, a higher dose of ivermectin does not result in the adult worms dying faster. It only keeps Buford from getting any more adult worms which will make his infection worse. I am attaching the following information from the American Heartworm Society ( https://www.heartwormsociety.org/images/pdf/Canine-Guidelines-Summary.pdf ). "In cases where arsenical therapy is not possible or is contraindicated, the use of a monthly heartworm preventive along with doxycycline at 10 mg/kg BID for a 4-week period might be considered. An antigen test should be performed every 6 months and the dog not considered cleared until two consecutive NAD (no antigen detected) heartworm antigen tests, 6 months apart, have been obtained. If the dog is still antigen positive after one year, repeat the doxycycline therapy. Exercise should be rigidly restricted for the duration of the treatment process." So, their recommendation is just to do regular heartworm prevention monthly (not higher doses of ivermectin) combined with Doxycycline for the first 4 weeks, then recheck a heartworm test in 6 months. At some point, if you keep Buford on heartworm prevention monthly, we expect that the worms will die and he will clear the infection. The worry is that the longer the worms are there, the more damage they can potentially do to the blood vessels. Good luck! I hope that was helpful and answered your question. Thanks for using PetCoach.

No. I don't think that would be wise. When they have been treated for heartworms and rested for 2 months, it is recommended to GRADUALLY increase their exercise. After they have been cleared to start exercising it is best to start out with like a 5-10 minute leash walk and then every few days increase the time by about 5 minutes. I know that outwardly she seems fine and healthy and I'm sure she'd love the hike but I wouldn't risk it. Hope this answers your question. Best wishes to you and Stella in the new year!

Captain should be fine to go back to his regular activities (dog park, etc.) four weeks after completing his heartworm treatment protocol. Until then, he should be cage-rested to minimize the risk of complications.

There is really only one treatment for adult heartworm disease which is given by injection. The other method is just continuing to use preventative medications so they don’t continue to be bitten and infected with more heartworms. The hope is over time the worms will die. This may take years and the worms will continue to do damage to the body while they exist. Heartworm disease is complicated and devastating and the treatment does have the potential for side effects. If Scooby does have heartworm disease then a long conversation with your veterinarian about treatment plans would be advised. American heartworm society https://www.heartwormsociety.org. Has some great information and resources as well. Best of luck and thank you for using Pet Coach.

Hi, thanks for using PetCoach! Unfortunately no. There is a slow kill method using oral Heartgard monthly but it can take a year or more and allows more damage to occur to the lungs of the dog. You would also need to get the medication for your Vet. Rocky would have to be exercise restricted for 1-2 years. The 3 injection technique using adulticide is the standard of care. Below is the protocol from the American Heart worm Society. I wish you and Rocky the best! https://www.heartwormsociety.org/images/pdf/Canine-Guidelines-Summary.pdf

This treatment could cause lethargy, it's quite common and this is one of the reason restriction is a must. if she becomes too lethargic you might need to take her to the ER, especially if you notice abnormal breathing.
