My dog licked or chewed a dead rat. Can he get sick? What to do?

There are a couple of diseases that a rat can give a person, but it's very unlikely it could be spread this way. Bacterial and parasitic diseases usually require a certain amount be ingested before they cause disease. It would take more than a lick to the outside of the mouth to give a substantial amount. There are some scary diseases like hantavirus that can be spread quite easily though. However, it is relatively rare. The best thing you can do to rule-out disease is by taking the rat to a state laboratory for testing. The government has disease monitoring laboratories that will examine and test the body for diseases of concern in your area. You can call your local vet, or Texas A&M veterinary diagnostic laboratory (https://tvmdl.tamu.edu/) for more information. Otherwise, I would not worry too much. It appears that you have done a good job washing away any potential contaminants and it would be rare for you to have contracted anything. If you happen to feel ill in the next week, then please contact your doctor and mention the rat incident. I hope that helps and all is well.

Examine your dog for any sign of injury due to the fight with the rat (if any). If any (which is likely, sometimes even inside the mouth) take him to your veterinarian for an examination. Disinfection can eventually be started at home with very diluted hibiscrub or betadine or salted water baths. Buster collar may be useful as well to avoid licking/scratching at the wound. If your dog is not vaccinated for Leptospira, take him to your local vet anyway. Antibiotics may be needed. Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

There are a couple things you should be concerned about, if your dog is not vaccinated then leptospirosis is a concern as Rats carry it and it is a serious disease in dogs (affecting the kidneys and liver). the main second concern is rat poison, if the rate ingested rat poison in the past couple weeks, then your dog could be poisoned too, these poisons are usually blood thinner which cause an animal to bleed to death, often it has a delayed action and the treatment for that is vitamin K, which must be given by your vet by injection first.

[Rabies](https://www.petcoach.co/dog/condition/rabies/) in rats and other small rodents is extremely rare. I would be more concerned with the possibility that the rat had been poisoned elsewhere and its weakness was why your dog was able to catch and kill it. Leptospirosis, an infectious disease that affects the liver and/or kidneys, is also a high risk from contact with rats. Other possible diseases your dog could contract from contact with rats are: • Rat Bite Fever (*Streptobacillus moniliformis* form). Dogs can be infected by the bacteria by biting or eating infected rats. Dogs do not themselves get sick, but serve as carriers for the infection, passing it along to humans. • [Tularemia](https://www.petcoach.co/article/tularemia-rabbit-fever-in-dogs) is caused by the *Francisella tularensis* bacterium. Rabbits, hares and rodents, including rats, are particularly susceptible to the organism, and often die in large numbers during an outbreak. If a dog eats a rat (or other animal) infected by this organism or drinks water contaminated by infected rodent waste, the dog can become ill as well as passing the disease on to humans. Symptoms in dogs include refusal to eat, fever, cough, vomiting, and diarrhea. If not caught and treated, it can lead to death. In humans the symptoms are specific to the mode of infection (deer fly, ticks, contaminated water, handling dead infected animals, etc.) but can include: chills, eye irritation, fever, headache, joint stiffness, muscle pain, ulcers on skin, shortness of breath, sweating and weight loss. • [Bubonic plague](https://www.petcoach.co/dog/condition/plague): dogs can become carriers of the *Yersinia pestis* bacterium if they are bitten by the flea of an infected rat. Dogs do not tend to be sickened by bubonic plague but can pass the disease on to human caretakers. • [Salmonellosis](https://www.petcoach.co/article/small-pet-rodents-can-pose-a-salmonella-risk-to-humans) can be transmitted to a dog that encounters the fecal material of rats, other rodents and especially reptiles. Symptoms in canines include: fever, diarrhea, dehydration and shock. Death can occur if untreated, and the dog can spread the infection to human through its feces.

The mouth is not the problem, the problem is if they ingested the rat or not and if they are vaccinated or not, these are the two important factors when dealing with a dog the kills a rat, the mouth is irrelevant. if your dog ingested the rat you must take him to the vet urgently, because of the high risk of rat poison (this will likely be deadly if left untreated), the second issue is vaccination, if your dog is not vaccinated he is in risk of contracting a disease called leptospirosis which can cause severe health problems and in some cases can be fatal as well.

Hello and welcome to Petco Pet Education Center, formerly Petcoach. It is very uncommon that the rat would carry a disease that you would get from playing with your dog after carrying the rat. If you would like to be very precautions I would recommend the following: I would suggest throwing the rat out so that Cookie can't find it again. You can wear gloves to do this, and also wear gloves and get some water and rinse out Cookies mouth very well. After this I would play with Cookie without any concerns. Best of luck with Cookie!

The main worrying fact is rat poison, if the rat ingested poison before he was killed by your dog, Gracy could be affected by it (it could be fatal). i would recommend taking her to your vet in order to get vitamin K coverage just in case.
