Someone is poisoning my dog

This has been going on for years now but I didn't clue in for the longest time and that is my fault. I allowed myself to believe the animal abusers I was living with at the time that "oh your dog just has anxiety". That's absolute bullshit and they know it. My dog lived with myself alone for years and never a problem. She lived with my aunt for a period of time and never a problem. She lived with someone I knows sister and never a problem. She has never had a single tiny indicator of anxiety ever accept until I started living with a couple individuals as roommates and then all the problems with the dog started. One of her eyes swelled to twice the size of the other one and I had a vet tell me that the eye was dead and needed to be removed with zero explanation as to why because they couldn't figure it out. Then she would suddenly smell her food in her bowl and be turned off by something and not eat it. It would happen for days at a time until she would finally force herself to because she was starving. The worst was yet to come. One day she would start sniffing and become very interested in certain spots on the floor. After what seemed like she licked it or interacted with the spot she would make these reactions like someone does when they taste something absolutely horrible. She would shake her face in disgust and sometimes she would start foaming at the mouth. And you can set a clock to this but within 5-7'minutes she would start whining. It would get worse and worse and worse. Then she would start screaming. Her temperature would go through the roof and she would start panting inside even in the middle of winter. It's the most heartbreaking thing to watch and it would go on for hours and hours. Usually between 7, sometimes upwards of 11 hours. After the first few hours she would no longer be jumping straight up and down howling begging to be picked up and held like she was terrified of something but she would start running around in circles in the apartment. She would do this for hours!!!! The poor thing looked like she was about to die from exhaustion. She would continue to do this until she literally collapsed on the ground because she no longer had the energy to move. They would do this to her someone's every couple days sometimes once a week sometimes they might let her off for a couple weeks if they had a lot going on. It's purely the behavior of an animal abusing psychopath. This is a video of what they have done to her. If anyone recognizes the symptoms and can tell me what to get her tested for so I can prove my case please get in touch. She doesn't deserve this. She is the sweetest, nicest, most innocent little girl and they have treated her like a science experiment and laughed at her as she suffered at their hands. https://drive.google.com/file/d/1JMjkKTP5N5xu5304J2hm5BEREFFTCyho/view?usp=drivesdk   Any information anyone can provide me with is good information. Anything to go on and at least somewhere to start.   Warning the video is hard to watch

Thankyou for your fascinating question.   I can see what has led you to this conclusion that someone is poisoning your dog.  This sounds to have been happening for a while - is there some circumstance between the humans involved that has led you to this conclusion? (Just for you to think about; you don't need to detail it here).  Rest assured that there are other explanations- indeed more likely ones, because it would be extremely unusual for poisoning to look this way ( with the dog was picking up something toxic from the floor and reacting immediately).   Toxins tend to take some time to act, unless something caustic was given that burned the soft tissues immediately  (this would cause lasting effects In the mouth that a vet would see and certainly not go on for years with normal behaviour in between times).  So I wonder whether it's worth considering alternative explanations. One that comes to my mind is a neurological episode, or fitting.  Traditionally we think of fits as sudden lack of consciousness and twitching, but not all fits or periods of abnormal brain activity present like that.  A period of frantic licking at the floor (perhaps a response to the nerves of the tongue not feeling quite right).  Indeed, licking the floor, head shaking, foaming at the mouth, circling, exhaustion.... Are all consistent with a neurological (brain-related) episode. There may be foodstuffs, or mineral shortages involved, but there are other possibilities too.  I know it's a scary word, but a tumours might do it or even some liver changes that then affect (indeed, mildly poison) the brain; cruelty certainly does not have to be involved.  A brain tumour might also explain any eye swelling, or a build up of tissue or fluid behind the eye. It sounds as this could all be rather distressing for your loved one, so my recommendation would be for your vet to examine your dog immediately, in order to start some investigations rolling.

I'm going to answer that again, in an easier to follow form.  The symptoms you describe - licking the floor, circling, fear, stress for no obvious reason, drooling.....   could all be connected to the brain.  This doesn't completely rule out poisoning or mineral deficiencies, but certainly doesn't rule it in; brain cysts, tumours, pressure changes etc are very common causes of such signs.  Indeed, the changes to the eye might also suggest that a "space occupying lesion" eg a lump or cyst in the brain.  The episodes that you are describing sound rather like seizure activity and this could be an important line of enquiry for your vets.  I wonder whether an MRI or CT scan might be available to you / helpful?  Even if not, a vet could take a very thorough history of this case and examine your dogs cranial nerves and may be able to either confirm what I'm saying, or come up with an alternative theory.
