My dog's blood test: low platelets, high white cells. Is she okay?

Updated On September 23rd, 2025

Pet's info: Dog | Cavalier King Charles Spaniel | Female | unspayed | 9.7 lbs

I would like to know if there is anything wrong with my little dog (1 yo). We made 1 blood test 20 days ago (first pictures) where her platelets (plaquettes) were very low so the veterinarian put her on Doxycycline and did an injection for Pyroplasmosis. Her leukocytes were at 7700 /ul then but now we made today another blood test (second picture), her platelets went a little up (still low) but her leukocytes went from 7700 /ul to 13400/ul... Is it normal ?

Hello, I am sorry to hear about Daisy. Based on the blood work abnormalities it is possible that Daisy has an infection secondary to tick borne disease or another organism. Many of these diseases cause destruction of the platelets. The white blood cells are part of the immune system and fight infection. It is possible that this value went up despite being on treatment secondary to fighting a severe infection. However, if Daisy is still not feeling well or these counts don’t improve it may be possible that Daisy’s platelets are low due to a different cause such as immune mediated disease. Your veterinarian can help assess for this kind of disease and determine if treatment is needed if Daisy’s blood counts do not improve or she is clinically ill. Hope this helps, good luck!
