What are the symptoms of PCB polychlorinated biphenyls poisoning in canines?

Polychlorinated biphenyls (PCBs) are a group of man-made organic chemicals that were widely used in industry and commerce from the 1920s to the 1970s. They were used in a variety of products, including electrical capacitors, transformers, hydraulic fluids, and paints. PCBs are persistent environmental pollutants that can accumulate in the food chain. They can cause a variety of health problems in animals and humans, including cancer, reproductive problems, developmental disorders, and immune system dysfunction.

In canines, PCB poisoning can cause a variety of symptoms, including:

* Weight loss

* Poor appetite

* Lethargy

* Skin problems

* Eye problems

* Respiratory problems

* Digestive problems

* Neurological problems

* Reproductive problems

* Cancer

The severity of the symptoms depends on the amount of PCBs the dog has been exposed to and the length of time of exposure.

If you think your dog may have been exposed to PCBs, it is important to take them to the vet right away. There is no specific treatment for PCB poisoning, but supportive care can help to manage the symptoms.
