Chocolate consumption by many pets, including dogs, cats, ferrets, birds and rats, can be extremely hazardous, a Kansas State University veterinarian has said.
Susan Nelson, assistant professor of clinical services, says that the ingredients contained in the sugary sweet can be very harmful for pets.

When a pet ingests a small quantity of chocolate, an owner may notice no changes, or they could see such symptoms as vomiting, diarrhoea and excessive thirst and urination.
As the consumption of chocolate increases, Nelson said the symptoms become more severe and could lead to irregular heartbeats, tremors, seizures and possibly death.
"Symptoms typically occur within 12 hours of ingestion. Unlike people, dogs take much longer to clear theobromine from their bodies, which leads to the formation of toxic levels," she stated.
According to Nelson, different types of chocolate can vary in the concentration level of theobromine.
Baking chocolate contains the most theobromine, white chocolate contains the least, and semisweet and milk chocolate contain a medium amount.
If a household pet consumes a large quantity of chocolate Nelson advises owners to call a veterinarian or emergency clinic immediately.
Inducing vomiting will most likely be advised, but she said this measure is not safe in all situations.
"Chocolate consumption is a very common problem amongst pets, dogs especially," Nelson said.
"It is important to recognize that individual reactions vary by pets, but it is best to assume your pet is one of the sensitive ones and not delay in seeking advice from your veterinarian.
"Be aware of the chocolate sources in your house, and tell any new dog owner about this potential threat to their pet," she added.
