Dog breathing fast, not on heartworm prevention. Is it heartworms?

Puppies breathe faster than adult dogs, up to 38 breaths /minute. You should get some wormer and worm your puppy. Round worms and other worms can cause puppies to get somewhat anemic, so their breathing rate can go up. Also pain (tummy ache from the worms) can cause an increased rate.

Any change in breathing warrants a trip to the vet for a recheck. While it’s possible that there’s nothing wrong, you could also be noticing the beginning of a complication of heartworm treatment. Pulmonary thromboembolism can occur when dying worms become lodged in the small blood vessels of the lungs. Your vet might want to take a chest x-ray.

It could be that Mighty is suffering from intestinal worms which are common in puppies and would give a bloated appearance to the stomach. I would give him a deworming treatment now, and another in two weeks to kill all the worms. He should then be dewormed monthly until he is six months of age, and should be dewormed every three months thereafter. As for breathing quickly when trying to sleep, this can be normal and I wouldn't be concerned about it unless he's breathing quickly all the time. Best of luck, I hope this helps!

Heartworm are know to lead to cardiac disease specifically pulmonary hypertension and blood clots to the lungs. Unfortunately, he is in heart failure until proven otherwise. Neither lisinopril or a thiazide are likely to improve symptoms of CHF significantly. Ultimately, he needs lasix if he is congestive heart failure. However, first a veterinarian must make the diagnosis. The best thing to do for George is the get him to the nearest veterinary emergency hospital as soon as possible.

65 breaths per minutes is an emergency, you cannot wait until Monday as she may very well not make it that far, you need to take her to the vet today. it could be related both to heartworm and the mammary gland tumors.

I would Holiday examined by a vet, as it's not normal for a dog to breathe heavy without exercise. It could be a tick borne disease, but it could also be a respiratory illness, heartworm disease, or heart disease among other causes that are leading to her symptoms. The vet can do a physical exam, blood tests, a urinalysis, and x-rays to diagnose what is causing his symptoms, and can treat accordingly.

I would be concerned about these signs even if they are related to heartworm disease, and would not consider this type of coughing as typical for a dog recovering from heartworm. If she seems to be having trouble breathing you should seek emergency veterinary care. A chest x-ray might be recommended depending on how Tess's chest sounds on physical exam.
