lola shivers when she is in pain!

She has a very sensitive tummy and if she eats anything that's not her kibble, like human food (specially if she has something with too much fat/grease.) then she will shake/shiver all day long, My vet recomended Digyton from Himalaya (it's all natural) and whenever she starts to shiver i give her that medicine and in 5 min she is completly fine.
