Canine Neutropenia

Let’s look at a case study of neutropenia in dogs. At a very young age, our border collie CLOVER developed seemingly chronic canine neutropenia. That simply means she consistently measured low — not dangerously low, but low — neutrophil counts. That’s a type of white blood cell. It’s kind of important.

Neutropenia in Dogs – What Happens Next?

We did all the tests that our veterinarians recommended for canine neutropenia when it didn’t looks like it would improve, including a bone marrow biopsy. That test revealed that CLOVER’s neutrophils remained low across all 8 stages of neutrophil development. So, she just doesn’t make many of them. It is NOT like she makes a ton of neutrophils that then get destroyed somehow.

So, good news … sort of.

Ultimately, in our case, chronic neutropenia in dogs never turned into anything.

  • Clover’s low neutrophil counts never got any worse, really.
  • She never developed another illness or autoimmune disease from it.

Low White Blood Cell Counts Over the Years

After many years, we basically stopped worrying about it. In fact recently, CLOVER’s neutrophil counts have improved, according to routine bloodwork. Here is the latest chart I’ve been updating all these years. The GREEN line is the low end of normal neutrophil count in dogs. The RED line is where it starts getting scarier.
