Topic: Generic vs name brand

Question:Hello I usually the heart guard plus for a 0-25 lb dog. I was wondering if the generic is the same thing because it is cheaper?

Answer:Yes, as long as it is the same active ingredient, in the same concentration, from a reputable seller, the generics work well too.

Question:Which is better...heartguard or interceptor?

Answer:They both work very well to prevent heart worms. Heartgard has been around longer but interceptor covers whip worms - they both cover some other more common intestinal parasites like hook worms and round worms.

Topic: Coverage from company

Question:Hi, I am looking to save some money on my Heartgard meds. I asked my vet for the prescription and she told me that if I dont buy it through a vet office the company wont honor their warranty if my pet gets heart worms while on the medication. Is this true? Its a new vet so Im not sure if this is legit or not.

Answer:You will have to call the 1-800-Petmeds phone number and ask them that question - I'm not sure.

Topic: heartworms

Question:I just picked up a dog from the pound. A jack Russell terrior. She is about 12 years old and is very emotionally and physically down. They told me she tested positive for heartworms. I am concerned a trip to the vet or a harsh treatment might kill her. What can I do?

Answer:The trip to the vet more than likely won't kill her and then discuss your treatment options with the veterinarian. Here is a link to a good article, written by another veterinarian from a site that I trust, about the various types of treatment options: https://veterinarypartner.vin.com/default.aspx?pid=19239&id=4951486

Topic: After Heartworm treatment

Question:I need to know when it is safe for a dog to get active after the third treatment.

Answer:After treatment, the patient must be strictly confined for one at least month following the final treatment - consult your veterinarian about your specific dog. No walks, no running around. The dog must live the indoor life. The reason for this is that embolism to some degree is inevitable and it is important to minimize embolism-related problems. Exercise increases heart rate and oxygen demand and we need the heart to rest during this recovery period.

Topic: Usage of Revolution

Question:I had boughten Revolution 85-105 pounds back in April of this year for my 5 year old boxer. At the time he weighed 93 pounds so my vet had me put him on a diet to get down to 75-80 pounds. He was weighed at the vets office yesterday at 77.5 pounds. My question is, I still have 2 doses of the 85-105 pounds medicine left. Would it do harm or hurt my pet if I used these last two doses on him the next two months seeing he is no longer in the higher weight group. This medicine is rather expensive and I would hate to waste these last two doses before I use the medicine for his current weight group, which I am ordering today. Any information or answer to my question will be greatly appreciate. Thank you very much for reading my question and God Bless You. Doug C.

Answer:That should be fine. Call the manufacturer (number or email should be on the packaging) to be 100% sure.

Topic: Low positive heartworm treatment

Question:Hello, I am looking to adopt a rescue dog who has tested positive for heartworms. The volunteers at the rescue assured me that he was "low positive", and that means that he doesn't need the 3 shots but instead is taking a pill for a month as treatment with no restriction on physical activity. I haven't found anything online supporting this type of treatment, so I suspect that they are actually giving him heartworm preventative which doesn't affect the adult worms. I wanted to ask if you are aware of any type of treatment option for "low positive heartworm" where only a pill is necessary or if you would suggest that he should take the 3 shots with restricted physical activity. Thanks!

Answer:The adulticide is usually more ideal (either 2 or 3 shots) but all cases are different. Here is a good article, written by another veterinarian, from a site that I trust, detailing both methods and their pluses and minuses: https://veterinarypartner.vin.com/default.aspx?pid=19239&id=4951486

Topic: Doberman following heartworm treatment

Question:We rescued a Doberman in July who already had heartworm the rescue group sent us home with doxycycline and as soon as he finished we took him up to rescues vet and they had him for 5 days to get his shots in his back. We have been told by one vet and rescue group to start him on heartworm pills Sept 1st and our vet not yet. What is your opinion? We are totally confused and dont want to hurt our little boy any more than what he is going through!

Answer:All heartworm cases are a little different (based on severity, age of patient, blood work, etc) but I usually start the heartworms pills before the adulticide so you will have to consult your veterinarian about this. (They may have given him a heartworm pill when they started the Doxycycline.)

Topic: Trifexis

Question:My dog has been on Trifexis for years. My vet has now suggested a monthly dose of Tri-Heart plus. Why is it necessary for 2 monthly heart worm meds?

Answer:It isn't - are you sure that's what they were recommending adding? Our problem with Trifexis is that it doesn't have tick coverage, so sometimes we have to add something for that. But, you are right 2 different (very effective) heartworm preventatives are unnecessary.

Topic: OTC heart worm meds

Question:can you recommend an otc heart worm medicine please?just prevention

Answer:They are all prescription (at least in the United States) because it is important to confirm with a blood test that your dog is negative for heart worms before starting most of them.

Topic: Medication

Question: My dog got her last dose of Trifexis on July 5th and is due for it on August 5th. I'm unable to get it by that date, will it wear off that day or do I have a couple of days to get her another dose?

Answer:It's pretty forgiving, a couple of days is usually no big deal, but keep it as close to one month as you can and just continue to test her about once a year.
