AS I think I've discussed here, Luna had developed some crazy behavior that we believed was linked to her low thyroid. It showed up mostly as fear of all sorts of things she was previously unafraid of-- the kitchen, the car, her harness, loud noises, the agility tunnels... You name it.
Once we got her on Soloxine (.4mg BID), those issues sort of melted away. Kitchen was no longer an issue, she harnessed up and rode in the car with no problems, and she became an agility superstar...
Protocol is generally to monitor the thyroid levels periodically, since they change as the dog gets older. We didn't do the full panel this time-- just an in-house SNAP test. And she tested just above normal. Not a LOT above normal, but enough that her vet wanted to see how she would do on the next dosage down (.3mg).
Within a couple of days, she seemed a little more skittish. Over the next few weeks, she didn't seem quite right, but I thought I was probably imagining it.
In the heat of this August, we bought a couple of sprinklers for the pups to play in out in the yard. Andre took to it right away. He loved it.
Luna stayed in the background barking. Finally, she decided to attack the sprinkler. It was pretty funny to watch. But her focus on the contraption was way too much. WAY too much. Too intense. Too obsessive. TOO. MUCH.
To make a long story less long, the intensity over the sprinkler was the last straw in a list of Very Exciting Things in Luna's day and it seems that she snapped. She and Robin got into quite a fight. Puncture wounds, a broken tooth, and hurt feelings. And keeping the two of them separated while we work on lots of classical conditioning and desensitization and allow everyone's hormones to reset.
And while we allow her thyroid medicine to kick back in. As many of you may know, a low threshold for aggressive behavior is one of the behavioral signs of low thyroid. The vet agreed to put her back on the higher dose, and as long as her behavior is ok and she's not losing weight, we're going to be happy with it, "Tests be damned," as he said.
And she is better. Much less fearful. Calmer. Happier.
So what does this have to do with her raw diet?
Well!
I started trying to figure out why her numbers were higher than they were the last time we tested over the winter.
One thing that might be contributing is the spirulina supplement. That has some iodine in it.
The other thing I came across was this study from the Journal of Small Animal Practice. Basically, this study looks at a number of cases of dogs who exhibited symptoms of HYPERthyroid and were fed a raw diet. Turns out, they received higher quantities of neck material-- beef gullets, etc.-- in their diet, which contained, in some cases, the thyroid itself, and almost unavoidably thyroid hormone and other material.
This winter, we pulled Luna off of chicken and began using turkey as her primary bone source. Necks are the cheapest and boniest cut for us. And they frequently get a mix of gullet and tripe. So she's received a lot of neck material lately.
So what does that mean???
Don't worry. It doesn't mean that we will be stopping the raw diet. And no it doesn't mean we're getting rid of necks altogether. And it also doesn't mean that this necessarily had anything to do with her higher numbers. She's a young dog. Frankly, she probably should run a little high.
But it is an EXCELLENT reminder to diversify the diet. We're adding in more turkey legs. I'm also researching sources for duck frames and rabbit backs. And we may revisit chicken for her. It was kind of a random stab at seeing if she's sensitive to chicken as one of her allergies. And I've increased the amount of plain tripe that I buy and less of the mix with gullet.
It's also a good reminder that adding supplements to a diet willy nilly has the potential to cause some unintended consequences. While iodine is really important, when you're trying to balance the thyroid medically, pharmacologically, adding things like additional iodine can skew all of that and put it higher than it needs to be. Alone, adding iodine wouldn't be enough for her. So she needs the soloxine. So it's possible that me adding the spirulina put her over the top. I am still giving it to her. I think its benefits are good ones. But if we still have trouble after diversifying the diet, I might rethink the spirulina at that time.
