My puppy has ticks and is sick. Is Bravecto safe for a sick puppy?

Updated On September 23rd, 2025

Pet's info: Dog | German Shepherd | Female | unspayed | 8 months and 16 days old | 66 lbs

So our neighbors dogs kept barking and we found out that they killed a opossum and my dog has been going by the fence to check it out and I think she got ticks from it because I found one on her and she’s been very depressed and tends to be aggressive at time is not eating but is drinking like crazy If I give her the bravecto pill will that kill them ? Please I’m worried she’s never had any

It sounds like Marley may be sick. Bravecto will kill ticks but if she is not feeling well, there is a high likelihood this medication will make her feel worse. We generally wait to give flea prevention to pets until they are feeling better. Additionally, you note that Marley only weighs 15 pounds but is a German Shepherd. This leads me to believe she is a puppy. Bravecto is not recommended in puppies as they will outgrow the weight range quickly. Instead you use a monthly product like Nexgard. I recommend to take her into your veterinarian today if possible. Depending on where you live, ticks can transmit many diseases and she may go on an antibiotic prophylactically. Drinking a lot of water can be a sign of a kidney or bladder infection as well. Large breed puppies however are prone to drink a lot of water and it’s not pathologic. You can’t know the difference however without testing the urine. It’s always better to be safe than sorry! I hope this is helpful and please feel free to post any additional questions!
