Hello. I apologize for the wait I had to step away to make dinner.
The symptoms you are describing do not really point us in a specific direction,
Shivering could be due to pain, stress or elevated body temp. Acting painful and shivering when moving and trouble going up the stairs could indicate a problem with a disc in the spine.
Disc disease is a common problem in small breed dogs both in the back and neck .
If what you are seeing is more her getting startled easily by things going on around her then we would want to get a good look at her eyes and ears to be sure her sight or hearing is not diminishing.
Now I can not rule out problems associated with this supplement you are giving. I spent an hour after you posted your question researching this supplement and I can tell you it concerns me. Some of the things that concern me about this supplement are
1. It contains Vit A, Vit E , Vit D and zinc but it does not give us the levels that each wafer or tablet contains. Vit A, D and E are fat soluble vitamins meaning they can build up in the body to dangerous levels. Zinc is toxic in certain levels and can cause neurological symptoms.
2. I do not like that this company is partnering with breeders and breeders are forcing buyers to sign contracts saying they will keep the dog on this supplement. This suggest a kick back program being given by this company rather then it being something that is actually good for pets.
3. They show no verified research behind this product and their claims.
4. It contains far to many different vit, minerals, herbs etc that if a pet had a reaction it would be almost impossible to know what it was to.
I personally would suggest stopping this supplement.If you want something that can help with the skin then go with an omega fatty acid supplement that you can get from your vet.
If after a few days of discontinuing the supplement you see no change or she becomes obviously painful or declines in anyway then I would have her seen by your vet for a hands on exam.
Try offering some boiled hamburger or chicken and rice. Elevate her bowl so she does not have to lower her head all the way. If she is willing to eat with an elevated bowl then I would be worried about a problem with a disc in her neck.
I hope this helps and she feels better soon. Please reply back if you have additional questions and I will be happy to help.
