Merrick - Herbal Extracts and Neurological Problems?

by Mel
(Tampa, FL, USA)

Does your new “natural” cat or dog food contain herbs such as rosemary extract, a neurotoxin that can cause neurological problems, seizures and anemia?

The real culprit in cat and dog foods may be rosemary extract, a natural neurotoxin. Adverse reactions, including seizures, can show up soon after ingestion but symptoms may also be delayed which complicates accurate diagnosis.

Holistic practitioners warn that herbal extracts, such as rosemary, sage, thyme, wormwood, dill, and mint, may be “mind-stimulating and “contributors to seizures”

MERRICK DOG FOOD IS LOADED with these ingredients! Help me petition Merrick to take them out! Dogs are not gourmets - they won't know the difference and the food will be safe!

I have sent email to Merrick.

WHY use these ingredients at all? The dogs don’t know the difference – only people think it sounds yummy. The dogs have to eat it!! It will lower their production costs and make a safer product!!!

See here for full article on this very interesting (and worrisome) topic:   Rosemary Extract, Pet Food Neurotoxin.

Bear in mind though, it's not only Merrick dog food. There are also other all natural dog food brands that contain these herbal extracts in some of their recipes.

If this is a concern to anyone, or if you're already dealing with dog seizures, we believe it's definitely worth paying attention to. As pointed out by our visitor, Mel, our dogs certainly are not going to notice the difference, and it's always best to err on the side of caution. When in doubt, leave it out!

If anyone else has any information on this subject, or if you've suspected a herbal extract, such as rosemary, has caused seizures in your own dog, PLEASE add your comments here.

Ditto for Seizures
by: Doxxymom

In April I started using a plaque and teeth cleaner on my Dachshunds. After a week of using, one of my Dachshunds had his first set of seizures.

After researching on the web and reading about rosemary extract, I picked up the teeth cleaner and there it was - rosemary extract.

I took him to the vet to make sure there wasn't another medical reason for the seizures and the vet said all of his panels were normal. He told me since he couldn't find anything out of the norm that he was epileptic. I have put off putting him on any kind of medication until I have exhausted holistic avenues. I put him on one of the top rated holistic dry dog foods after researching them. He had more seizures. I looked into the ingredients on the dog food company website and yes, the bag of food I bought had rosemary extract in it too. The product line I bought was the only kind in their large variation of products that had the rosemary extract in it. So now I will be dumping $45 worth of dry dog food. I will replace with the same brand since it is a good holistic choice for kibbles but I will make sure there is no rosemary in it next time.

Don't assume because one flavor doesn't contain rosemary that none have it. Could be a costly oversight as it was with me. I am going to continue with natural kibble food and herbal supplements to try to relieve my dog from these seizures. I do believe that the rosemary extract set his seizures off and feel that this ingredient should be removed from all pet foods and products.

UHHHH?

Who told you this stuff was bad for dogs? I have been in vet school for 2 years and never heard anything to this effect in ANY class I have ever taken. Mint is fantastic for dogs!!! Rosemary is one of the few herbs dogs can eat! A lot of veggie treats contain rosemary, and many holistic and herbal dental products use mint and rosemary!

Shih Tzu Seizures
by: Anonymous

All started when I realized that a combination of Iams and Cesar dog food wasn't the healthiest thing to feed our dog (for around 9 years): in fact it was probably the worst brands combined. Plus he was often sick most mornings and would throw up his food.

Anyway, swapped him over to Artemis Fresh Mix Small Breed and Wellness canned food and he seemed to feel a lot better.

A few months into his new diet he one day flopped on the floor and convulsed. We literally thought he was dying.

Took him to a vet, they diagnosed him with epilepsy because of his breed. Before that though they wanted to do a $2,000 dollar scan to make sure he didn't have a brain tumor, which I declined for obvious reasons. I even BROUGHT IN HIS ARTEMIS FOOD to see if there were any ingredients that may be contributing to his seizures. They said the food was fine. Stuck him on Phenobarbital. Pheno made him hungry, tired and changed his personality pretty drastically.

Six months later, I'm here today. I decided to do a Google search just to completely rule out that it wasn't anything in his food. Found out that Artemis contains, yep you guessed it, Rosemary Extract. I threw his food out last week, hasn't had a seizure since although I'll be keeping a close eye on him. Next is to slowly get him off his Pheno. If he still has seizures after that then I'll know it's probably genetic. Regardless, I'm surely not going to feed him more Rosemary Extract, especially as much as he ate with his increased appetite on his Pheno! Talk about counteractive, my god.

Anyway, just found this article today and it basically just takes the words right out of my mouth. This should really be a red flag ingredient, maybe even more so than the preservatives and by-products found in other dog foods. Switching over to Wellness Super5Mix Small Breed.

I really am a living example of everything in the article. I just wonder how many other people are unknowingly doing this to their dogs. Like in my case, my own Vet didn't even know about the dangers of Rosemary Extract. Goes to show that "Natural" can be just as bad as all the fillers and toxins at times.

Rosemary
by: Danyelle

Hi,
I was reading your comments about side effects regarding rosemary in dog food. Do these apply to oil of rosemary?

Hi Danyelle -

Yes, these side effects appear to also apply to oil of rosemary.

According to an article entitled "Plant-induced seizures: reappearance of an old problem", published in the Journal of Neurology Volume 246, Number 8, 667-670, DOI: 10.1007/s004150050429:-

    "Several plant-derived essential oils have been known for over a century to have epileptogenic properties.

    A survey of the literature shows essential oils of 11 plants to be powerful convulsants (eucalyptus, fennel, hyssop, pennyroyal, rosemary, sage, savin, tansy, thuja, turpentine, and wormwood) due to their content of highly reactive monoterpene ketones, such as camphor, pinocamphone, thujone, cineole, pulegone, sabinylacetate, and fenchone."
