Pet Rats/cookie has a infected tooth

my dog and cookie  
Today I was playing with Cookie  and Freckles and noticed she had a lump, I looked and noticed her bottom left tooth was oozing puss and had a funny smell I dont know what to do about it and im concerned could you please help me.

Your rat and your dog are so adorable!  Poor Cookie.  She has an infection of some kind in her mouth or nearby it.  Foul odor is a sure sign of infection.  It may not necessarily be in her tooth or gum but somewhere in that vicinity.   Is her tooth loose or crooked?  Regardless, she needs antibiotics ASAP.

Can you take her to a vet?  She needs to be examined to determine if the lump is not something even more serious.  I recommend having the vet prescribe an antibiotic for the infection, such as amoxicillin, or another broad spectrum antibiotic.  Whatever antibiotic your vet puts her on, you should see some improvement within the first three days.  If you don't, change to a different antibiotic.  The vet can also give you a painkiller such as Metacam perhaps to ease her pain, as I imagine she must be hurting, poor girl.  Until you can get to a vet, you can purchase infant ibuprofen drops at your local pharmacy and give a tiny drop or two once or twice a day as needed.

I hope your little girl can be seen by a vet soon and recovers quickly.  Please write me again if you need any more help.

I can answer a variety of questions regarding adoption and care of pet rats throughout their lifetimes, including questions about their health and well being, temperment, diet, bedding, cages, toys, etc. I will try to answer your questions to the best of my ability in a timely manner and I have an abundant amount of resources to help me to help you with your pet rats. I love rattie pictures, so include pics with your question if you can. You may ask me medical questions, but please be advised that I am not a vet. I may use my resources to answer some medical questions, however, I will need to refer you to your local vet with medical questions that I feel I am not qualified to address.


I have been a huge rat enthusiast for many years. Since becoming a rat owner, I have educated myself in all areas of pet rats from every resource I could find including the internet, books, conversations with local exotic vets, as well as several local rat breeders.

I have a college degree but not in the area of animals. I have obtained my extensive experience and knowlege of pet rats all on my own because in my eyes, pet rats are the most interesting and fascinating creatures you can ever imagine to have as pets. I also am saddened by how mislabeled and misunderstood these amazing and extremely smart animals are by the majority, and my mission in life has become to educate and change as many people's perceptions of rats as I possibly can.
