side effects of flea/tick/hearworm meds.

From the time Django was a puppy, due to a beef allergy, his vet put him on Revolution for flea/tick/heartworm. It wasn't until several months ago that I noticed when I give him his Revolution, he was out of commission for the day. He would sleep all day, a little out of it, not in a good place.

I talked to his regular vet, his holistic vet and the behaviorist about this and they were aware of dogs having this issue however there really is no alternative to the medication other than to not give it to him and that's not an option. Has anyones dog had an issue with their dog and flea/tick/hw medication?

When Colbie started flea/tic meds (she uses Vectra 3D) she had a similar reaction. From what I have read it happens frequently.

The problem with these meds is they're geared for a huge weight range.

In a pill geared for a 11-20 pound dog, there is a 100% increase in weight from lightest to heaviest within the range. The dosage is based on the heaviest weight. So the meds in a pill that covers 11-20 lbs. is actually calculated for a 20lb. animal. If you have an 11 lb. dog it may be getting twice what it really needs.

Our solution is the vet switched her to the 1-10 lb. dosage (she weighs 10lb and change) and so far there have been no issues. There are also compounding pharmacies which can custom make the dosage geared to your dog's weight.

I use Heart Guard and Advantix II for both my pups with no problems (knock on wood). I know Advantix and Heart Guard are both dosed by weight so Tim and Mae are on different dosages of Advantix but the same for Heart Guard with goes up to 15 pounds before it increases. I need to be very careful with the Advantix around my cats since it's lethal if the cats ingest it but there is no grooming parties around here and they sleep in different spots so it's worked out. If I'm even one day late with Advantix I find ticks on my guys which is crazy so I need to use it every four weeks in warm weather and I did every six weeks over the winter. I also use Heart Guard year round too, which I kind of think is over kill so I'll have to reconsider this winter. Do you think Django's health issues could be playing a part with his reaction?

I have always given Django the dose for 1-10lbs. regardless of his occasional weight gain. He fluctuates between 10-11 pounds. I worry about cutting the dose a bit, will it still be as effective?

Keeper had a severe reaction to Revolution some years ago, when it first came out. He had every symptom on the list of possibles, except for seizure and death. We had to shove food down his throat for two months to keep him alive. He trembled so much, he couldn't stand still to eat.

It took him several years to get over it completely. We had him neutered when he finally got straightened out.

He's twelve now, and you would never know anything was wrong with him. He plays fetch with the rest of the dogs, and gets the ball sometimes, which is rare for any of the others with Posh in on it. Posh gets the ball 19 out of 20 times with the whole pack going after it.

Pam stopped giving any of the combinations, and Keeper has never had anything since his trouble.

I was recently researching tick medication. Maggie's a year old and I found a tick on her over the weekend. It was so tiny. Hubby doesn't know how I found it in all the fur on her shoulder. We don't have fleas at our VA or NC yards. Our vet wanted me to start Maggie on Frontline. I bought the tick/flea spray from vet's office but still not brave enough to use. I don't know if the every 2 week spray is worse than Frontline once a month. It one of those catch 22 decisions.
I hope more will chime in with their experience on what to use.

I give Kodi Heartguard for heartworms, but I only give it every 6 weeks, and only during the part of the year that mosquitoes are active. I use Advantix for flea and tick control, but I NEVER give it within a week of giving the Heartguard, and I use it as infrequently as possible. Ticks are a bigger problem around here than fleas, and I use the Advantix only if I actually see ticks.

I give my 3 dogs Heartguard monthly for heartworm. I use Vectra 3D for fleas and ticks only during June-October and only on my 2 big dogs. I don 't use flea/ tick stuff Leo at all. So far that has worked to keep fleas and ticks off the dogs and out of the house.
