8. Chocolate poisoning 

Since it’s always been known that chocolate is toxic to dogs, you should not give your pet this particular food. Be aware that this isn’t a fatal disease! However, studies show that less than 100g of dark chocolate can kill a 20-pound dog. Symptoms that include chocolate poisoning are increased urination, shaking, and vomiting. Make sure you call your vet if, by mistake, your dog ingests some chocolate you left on the table!

9. Fungal Infections

Most fungal infections are minor issues, but others can be quite serious and even deadly in some cases. A fungal infection usually affects only the skin and is easily treatable, but in cases where the entire body is affected, a thorough investigation may be required. Valley fever and cryptococcosis are the most dangerous fungal illnesses.
