Introduction

Hypothyroidism is the most common endocrine disorder of canines, and up to 80% of cases result from autoimmune (lymphocytic) thyroiditis. The heritable nature of this disorder poses significant genetic implications for breeding stock. Thus, accurate diagnosis of the early compensatory stages of canine autoimmune thyroiditis leading up to hypothyroidism affords important genetic and clinical options for prompt intervention and case management.

Tick Paralysis story

Tick Fever…. Something to know if you have dogs

This past Saturday a.m., my 5 year old Tibbie “Tami” was paralyzed in her rear legs when she woke up. They just were collapsed under her. I rushed her to the vet & he was able to get deep pain response from both back feet,
though 1 leg just dangled & showed no reflexes.

She was knuckling over on both rear feet & could not place them flat on the floor. She was alert & without signs of pain. Vet examined her & could find no injuries or sensitive areas & thought it was a back injury & she was put on dexamethezone 2 x daily & crate rest.

There was no improvement Saturday or Sunday and she had peed in her crate & was soaked.  I gave her a quick bath & put fans on her to dry her. Sunday nite she had a little response in her rear legs, but could not walk.

Monday morning she stood & took 2 steps before her rear legs collapsed. She made steady improvement  & by Monday night walked about 10 feet in the yard, peed, walked a couple more feet & had a BM.
I thought she was on the mend. Tuesday morning her rear was as bad as it had been on Saturday.

She started showing weakness on her front legs & between Noon & 2:00 pm her front legs became paralyzed & she started having heart arythmias.
She began drooling on the ride to the vet office.The vet did back and neck  Xrays = everything was normal.
He drew blood & while we were waiting for the results he told me he didn’t know what was wrong.

By this time it was 5:00 pm.
The bloodwork showed a high white count, pointing to infection. Vet was petting her & feeling her all over & couldn’t understand why she was not in pain anywhere.

He found an engorged tick under her ear – its color was identical to her coat. Then the AH-HA moment – tick paralysis!

In his over 30 years practicing, he had only seen 2 cases. His other vet who was working with him has been a vet for
about 10 years & had never seen a case.

He removed the tick, put her on Amoxicillin 2 x daily & said she should be sitting up by evening & recover.

The tick can have a neurotoxin that is released while feeding that causes this.  It can lead to respiratory failure & even death! … different sources say in the U.S. that death rates are 5% or 10-12%.

By around 8:00 pm Tami was improving in the front legs & could lay upright on her front. She steadily improved overnight & could walk wobbly by Wednesday morning. The vet predicts a full recovery.

I don’t think she would have made it through the night without that tick being removed.

Permission to crosspost. I will be sending this to all the Groups I
am on as I can’t remember this ever being mentioned.

Dogs on low-cal diet lived 1.8 yrs longer: study shows

ScienceDaily (Apr. 20, 2007)  Changes caused to bugs in the gut by restricting calorie intake may partly explain why dietary restriction can extend lifespan, according to new analysis from a life-long project looking at the effects of dietary restriction on Labrador Retriever dogs.
