Why does my dog have ticks if he's on Nexgard? What can I do?

Updated On September 23rd, 2025

Pet's info: Dog | Golden Retriever | Male | unneutered | 6 months and 9 days old | 50 lbs

When brushing today I found (what I think is) a flee, actually I pulled 4 or 5 out with his brush. He has been on nexguard for about 3 months now so not sure how he got them. We gave him a salt water bath followed by washing him with shampoo that is supposed to get rid of flees, mites, and ticks. Hoping someone can help me identify what I found and give some advice on how to permanently get rid of them. We have all tile floors and only our couch is upholstery.

This is a tick. The picture is not detailed enough to identify the exact species of tick, but no need to worry about that at this time. Since you have given Nexgard (which should kill ticks), then there are two things that could have happened. 1). The ticks were dead when you removed them. If they were not wiggling around and came out easily, then they were dead. 2) The Nexgard didn't work. It happens sometimes that the product (for some reason) didn't work. In that case you can just try a different product that is labeled for ticks. Sorry, I can't recommend any single product. There are so many and none that I know to be better than the other. If you try a new product, then just make sure it is only applied after the Nexgard is next due. I hope that helps.
