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?

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!
