Hello Niki & welcome....I agree w/ the others...Your girl needs a doctor....
Your girl is not depressed or bored...She's in PAIN and doesn't feel like eating...
The spasms and the unwilling to get up are clear indications of Joint or Spinal Pain....The limping fits, also....
Please, make her an appointment with your Vet ASAP....This may just be a case of Arthritis, but your Vet needs to prescribe Anti-inflammatories for her....They work wonders and will give her an excellent quality of life.....Dogs get Arthritis just as we Humans do!
Don't make the mistake of trying to treat this yourself......The prescription meds. from the Vet are the safest....Once you get her pain under control, she will feel like eating.....
Don't wait too long....As without food/water, dehydration occurs (Especially in a small dog) and can be Fatal......
Let us know what you find out & how she's doing...Good Luck, Karla
Definitely need to be seen by a Vet. Due to the age of the dog, any number of things could be going on.
I doubt she is depressed. Could be anything from dental issues to something internal or systemic.
you need to take her to a vet as soon as you can. she has a problem going on and like you if you was sick you would need to see a dr. they are no different. we can not tell you what is wrong with her over the net. plz take her to a dr now
