It seems she got the machine bottle of my night stand and ate one pill because I found the other

hello, So sorry to hear about your dog. This can cause your dog to have a high heart rate and have other issues. If you notice anything abnormal, it would be best to see your vet. They can treat your dog for toxicity. I hope that your dog starts to feel better soon.

My 80 lb GS chew through a bottle of methylphenidate. I estimate he ate 350 mg. What is a lethal dose? It's been several hours I just discovered the chewed up bottle

If you suspect that Sarge consumed 350mg of methylphenidate (Ritalin), at 80lbs we can say he consumed around 4.375mg/lb; the severity of symptoms and toxicity isn’t so much related to the dose but whether or not an extended-release formulation was consumed, one dog in the study in the second link below died after consuming 4.64 mg/lb. I would strongly recommend visiting an Emergency Veterinarian or calling the Pet Poison Helpline for more information regarding specific product information, timeline (very important) among other factors.

Hyper active Lab. Occurs during AKC field trials. I think due to the excitement of the event. Lots of people, guns etc. This is a hard working hard running retriever. He is at the Master level but sometimes he just boils over and forget's everything. Forgets his casting and will occasionally break at the line. He is fine in training and hunting situations. Only occurs during field trials. We have given him xanax with no effect. Considering some kind of ADD medication ? Any idea's would be appreciated. Rick

Firstly hyperactivity and hyperkinesis needs to be distinguished, but if the effects are only during certain situations then hyperactivity is most likely. There are some medications which may be useful, but I am not familiar with their use for this purpose; I’ve added a link at the bottom to some useful pages, but it would be best to discuss this with your Veterinarian or a Behaviourist which may be more familiar with this problem.
