Do shock collars cause cancer?

My last two dogs both had shocker collars and both dogs diagnosed with lymph node cancer. The first one wore a shocker collar to keep him in the yard, the second dog wore a shocker collar to control her barking. Do shocker collars cause cancer in a dogs throat?

I was searching the internet 4 articles on the correlation between invisible fence and canine cancer. I lost my beloved Shepherd at 8 years old due to cancer of the cervical spine. My 12 year old mixed breed Norwegian Elkhound was diagnosed with cancer today. One might think 12 years old is old but for a dog that size she should have lived in several more years but she only has several more weeks. When my shepherd was diagnosed with cancer I started trying to figure out a reason why. He drank bottled water most of the time, I cooked his food and was diligent about his care and vet visits. Both dogs need their boundaries so they never had to be shocked by the collar for overstepping their bounds but they still wore those colors so that they would not leave the yard and run into the road. The dog who is terminally ill hasn’t worn a collar in a year but she did have an invisible fence for many years before that. Now I’m suspicious enough that I will never be using invisible fence again. I adopted a two and a half year old Shepherd mix a few months ago whom I did not train on the collars. I would prefer to err on the side of caution. I will not be putting in an invisible fence in the house I’m moving to next month. I will be looking into a 6-foot fence instead and if the township will not allow it because I have a historic home then he will have a little less free run time but hopefully it will keep him healthier.

I’m so sorry, Cheryl. I understand why you are wanting to find out why your dogs were both diagnosed with cancer and why you may correlate them to the shock collar. I noticed you mentioned your dog drinking bottled water. I have not done any research on it myself, but know some people who firmly believe drinking bottled water attributes to cancer diagnosis. As I said, I have no knowledge behind bottled water and cancer but thought it may be something you’d like to consider as well and research more of.

My dog was recently diagnosed with lymphoma. Mass is in neck jaw area. Right in the area where bark collar sat. He wore a bark collar for a short time after I moved into an apartment. Not for long periods of time and only when I wasn’t home. He never had health problems. Is a happy dog. Excellent diet. No bad habits. He is a mixed breed rescue dog. Has been my best friend for 10 years. He listens to everything and keeps it all to himself! I cannot help but wonder if the bark collar contributed to this. ESP after reading these stories. Are these products tested? I wish I had never put it on him. He has been given a month to live. My heart is broken.

Oh I am so sorry to hear this Lu Anne. Please know we are thinking of you and your dog and hope you can make the most out of the time that you have left with him.
Our 7 year old Kelpie has been wearing a shock collar for 4 years or so now, just noticed her lymphnodes are up in her neck a week ago now.. took her to the vet yesterday & we’re awaiting results… signs are showing cancer, so the vet says. Fingers crossed… we’ll find out on monday.
Our beautiful hound dog was diagnosed last week with very aggressive lymphoma and he wore a boundary shock collar for 6+ years. The lymph nodes on his throat where the collar shock pins contacted him were the ones that engorged first. He also had vestibular 2 years ago, which also nearly killed him. Coincidence?
I also have a german shepard who has worn a in ground shock collar for 4 yrs now and just today was diagnosed with lymphnode cancer. Quite suspicious how all these dogs had shock collars and just happend to get lymphoma …..
We found a lump right where our samoyeds invisible fence collar sits 4 weeks ago. I have been meaning to get her in but due to the holidays I kept putting it off 🙁 just took her collar off tonight and the lump is 4x the size if not more 🙁 I am certain the outcome is not going to be good. Had I known it would have caused cancer I would have built a fence 🙁 I am going to have some heart broken kiddos if it’s cancer
Hi there. I have a pup who is a year and a half. We have used a shock collar with her on and off since she was about 8 months old. Last week, a lump appeared on her neck about the size of a loonie, and within two days it had tripled in size. We were at the vet today, a sample has been sent away to pathology. The lump appeared EXACTLY where the shock collar sits when she has it on. We were hoping to hear it was a ruptured salivary gland but when the vet returned from inspecting the sample under the microscope, it was not the case. We will be expecting to hear results later this week, but I couldn’t help but investigate a bit further to see if there were any connections.
Our Dutch Shepard was just diagnosed with cancer in her throat area. She has worn a shock collar for 6+ years. We did not use an invisible fence though, just a remote. Seems interesting it occurred in this area. She was my daughter’s service dog and we had to put her down today.

I am so sorry for your loss Rodney. My thoughts are with you.

I find no evidence online about shock collars causing cancer yet my dog has a tumor where his shock collar was. I am thinking that there is going to be a big big coincidence when he has what your dog has. Thinking maybe we should all get together and contact a lawyer.

Judy, so sorry to hear both your dogs have cancer. Studies show that shock collars can result in distress in dogs but stress shouldn’t be a factor in the cause of Cancer in pets. Cancer is passed down through genetics so depending on the breed it could be that or other environmental conditions including poor diet exposure to smoke, pesticides,
UV light, pollution etc. Hope that helps and sorry again about your pups!
