Cobalt F. Milanowski, M&M

Situation

On 09 Dec 2013 at 1200 MST, Cobalt Foxunit Milanowski, my greyhound, died at a kennel. A staffer at the kennel passed the hound before letting some other dogs out and noticed he was laying around like greys typically do. A few minutes later he returned and noted blood was coming from Cobalt’s mouth. The kennel called several veterinarians and determined Cobalt died quickly and peacefully in a matter of minutes. The kennel called me immediately. I was mid-flight, returning home from a vacation and planning on picking up the dog that day.

The kennel offered to cover a necropsy. The logical side of me that wants to know what happened also told me to let go and let Cobalt have peace. The idea kept turning over in my head; ultimately, my clinical compulsion won and I ordered the autopsy.

Background

Cobalt had swelling on his right rear ankle on 12 Nov 2013. He saw a veterinarian on 16 Nov. The vet’s differential diagnosis included valley fever, a tick borne disease, and osteosarcoma.

A blood panel came back negative for valley fever. Rather than run a tick panel, doxycycline was given prophylactically to treat any tick borne illnesses. A radiograph displayed cortical bone loss which is a sign of canine osteosarcoma. The vet recommended we periodically x-ray the site to insure the loss did not become greater.

The swelling reduced some, but resumed a day before the vacation. My plan was to make a vet appointment for him upon my return, but death intervened.

Cobalt’s past medical history includes a heart murmur when dehydrated, a bout of vomiting (which was never diagnosed, but resolved itself), and cryptorchid which was resolved surgically before we adopted him.

Assessment

Another vet performed the necropsy. Upon gross examination the vet observed petechiae on the abdomen and free blood in the abdomen and thoracic cavity. He found a tumor on the left atrium (hemangiosarcoma). The disease typically begins around 8-10 years of age. Cobalt was 7; he was detrimentally precocious.

The vet reported Cobalt likely had an underlying malignancy which triggered an autoimmune storm.  A cascade of events occurred in a matter of hours and Cobalt’s death occurred in a matter of minutes.  His end was sudden, quick, and peaceful.

Recommendation

A hemangiosarcoma would not show up on radiographs and would only be visible on an ultrasound. If the disease was detected in its very early stages, then treatment might have been a possibility. Chemotherapy would be performed in addition to a very vexing and delicate surgery to remove the tumor from Cobalt’s atrium. Even with surgery and chemotherapy the hound’s life is only extended by 8-9 months. Furthermore its treatment is generally limited to the expertise of a veterinary cardiologist, something not found in Flagstaff. Cobalt’s life might have been extended, but at what cost to the dog’s quality of life?

Given there were no outward signs nothing could have been done. Even if the disease was detected, at this stage the animal’s death could occur at any time. Early detection is the key to cancerous conditions in both humans and animals.

I am grateful for Cobalt. I am also grateful he did one last thing for me and expanded my knowledge of canine health. I miss my hound. Hopefully his dog brain was able to understand that my wife and I love him dearly.

Mammalian Dive Reflex

When the face is submerged in cold water the heart rate is slowed and peripheral blood vessels constrict.  This reduces the need for oxygen and allows for extended stays under water. It is known as the mammalian dive reflex.  The effect is mild in humans, but exceptionally useful in near-drownings in cold water.  Killer whales capitalize on the effect by holding their breath for up to 20 minutes.

This year I experimented with this reflex when I took the Polar Bear Plunge to raise money for the charity, American Greyhound.  January 1st, 2013, I will once again dive in freezing water to raise money for some adorably lazy, but fast dogs.  If you would like to donate to rescue retired racing hounds, then please do so here.  I am excited to experiment again, but I am more excited to help the second fastest land animal.

I'd do the plunge, but I can only doggy paddle.
