I am total agreement. When my dog Chester was successfully treated with Immiticide last year, he was given a full course of prednisone for joint inflammation and pain. It did wonders. Unfortunately, the drug that's used (Immiticide) is a form of poison and pain management is important here. Your vet should be made aware of what you are observing so that his pain levels can be addressed.It's a tough row to hoe, but when it is all done, it's wonderful!


Poor doggie :(

hope the dog feel better soon

Elizabeth & The Lab Crew

I do hope the dog is doing better. However I am always amazed that someone will write to a blog writer ( even if he is a Vet ) to ask for advice on a issue like this rather than call their own vet "right away"..


Hello, Elizabeth and Crew,

I also am amazed. Most of my replies advise these folks to let their veterinarian know what is happening. When we don't hear from the client, we think everything must be okay.

We try to call our clients back in a day or two to see how things are going. It blows my mind when they are having much worse problems, but didn't call us to let us know.

According to my opinion heartworm disease is completely preventable. A number of different products with excellent safety profiles are available. Tragically, some studies indicate that a minority of dogs and cats receive the preventatives as they should. Animals in the majority now are at even greater risk.

I am glad I found this page. My lab just had her first treatment today and she is very restless and only lays down for a few minutes at a time, she is very careful getting up to stand and very slow to lay back down. She has not eat anything since I picked her up from the vet. They did give her tramadol to give 2 pills every 8 hours for pain and 2 benadryl, It seems to help a little but not much. I have cried all evening thinking I have done the wrong thing by having this heartworm treatment done. I had a little dog that had heartworm treatment done 7 years ago and he died,I was very scared to do this with my lab. But the vet said she had to have it done and she is 3 years old and should do well, my Fred was 9 and a half years old and a cocker mix. I still feel the guilt of choosing HW treatment for him and I miss him still. I have prayed for Annabelle to be ok through this.


Hello, Sally,

I suspect by this time that your dog is feeling better. The soreness rarely lasts more than 24 to 48 hours.

You might ask your veterinarian about increasing dose or frequency. We usually give one 50mg Tramadol tablet per 20 pounds of body weight, up to four times daily, if needed. Dogs absorb Tramadol poorly, so require much larger doses than people of similar size.

I am rescuing a whiten terrier from a no kill shelter he tested positive for heartworms anf has had his first treatments unfortunately he is not doing so well with his mobility with his back legs the vet tech seems to think it could be a underlying condition such as a tumor, because usually dogs will regain strength within a couple of days of treatments he has not. He is eating and drinking has anyone had an experience where there pet took longer to gain strength


Hello, Valerie,

Even with dogs that have had very severe pain, all of my patients have gotten back to normal within 2 or 3 days. If your dog is having problems for longer than that, he should be evaluated by your veterinarian.

I have a small Terrier that I took possession of
Taking her to get neutered and shots, found she tested positive for heart worms
Her first shot, in 24 hours she was much better off
Now she faces the second shot
She is a little over a year old
Can I do compresses or ??? To help ease the muscle pain ???


Hello, Deborah,

Cool compresses may help. You should ask your veterinarian about pain medications to help. We do this routinely with our heartworm treatment patients. Some don't seem to need it at all, but others can be quite painful.

My little rescue from San Antonio Texas tested positive for heart worm even though he was negative when we adopted him. He is just finished his first injection today and is very restless; repositioning himself every couple minutes. Given him tramadol but apparently not helping. I am a nurse, the way he is acting looks like patients that are going through withdrawals from chemical addiction. I wish I could ease his discomfort. Fearing tomorrow as he will be getting second injection:(


Hello, Kathleen,

Be sure to let your veterinarian know about this. Sometimes we can add acetaminophen or gabapentin.


My rescue just had the two injection slow kill done. I’ve had him home for an hour and he seems pretty calm laying outside but after ten minutes he wants back inside. However, inside he keeps getting up and repositioning every few minutes and crying. The vet said to start all his meds tomorrow morning. What can I do to help with his discomfort? I would try ice or a warm towel but there is no bald spot so I’m not sure where the injection was done.



Hello, Meghan,
Sorry I didn't get to this earlier. I hope your dog is feeling better now.

The injections are usually given in the heavy muscle of the lower back.

A cold pack (not actual ice) would probably have been good. I usually send home Tramadol. Since we give them a cortisone type drug, we can't use things like Rimadyl (NSAID - non-steroidal anti-inflammatory drug), as they don't play well together.

Sorry I got behind.


I was so scared to get my dog treated. After the Doxcycline I actually paid to see if by some miracle she was clear, but unforunately she was not. She just got her first shot and was in a lot of pain all night - it was awful. I am already dreading the 2nd and 3rd shot in October. I am going to call the doctor to make sure they take care of her, but am reluctant to keep her overnight as they suggest for shots 2 & 3. Suggestions? Is the 2 & 3 shot less painful, and are complications from dying worms less or more?


Hello, Lucille,

I understand your concern. The amount of pain experienced by different dogs is unpredictable. Some appear to feel nothing, while others have an experience similar to yours.

I would expect a similar degree of discomfort from the next injections. As far as the complications from the dying worms, we probably see fewer worms dying the first time, so it might be a little worse next time.

Is she taking prednisone for the inflammation?

What type of pain medicine was dispensed after her treatment?
