Why does my spayed dog act like she's in heat every few months?

Updated On September 23rd, 2025

Pet's info: Dog | Australian Cattle Dog | Female | spayed

My 3 yo desexed female Australian Cattle Dog has a recurring problem. Every 3-4 months she will try to escape and shows strange behaviour, rapid panting, pacing aimlessly, eyes darting. This last about 3 days then she returns to normal behaviour. Can this be a mental link to her thinking she is in season?

That is unusual behavior for a dog but I do not suspect it is related to her mentally thinking she is in heat. That being said, dogs can have a heat cycle if they were not spayed properly or if they have too many ovaries. Your veterinarian can preform a simple blood test to determine if ovarian tissue is present. Next time she exhibits these symptoms, have her seen while she is showing signs as a blood test is more likely to find evidence of ovaries if they are present. That will at least rule that out. Other potential causes could include Addison’s disease or anxiety. I hope this helps and please feel free to post any additional questions.
