Shivering Dog

I am sorry to hear Tiny isn't feeling so great.  It is hard to say for sure what is going on with your dog but shivering can be a sign of discomfort.  I do think the weight loss and the inactivity could be cause for concern.  I feel it is most often best to take out the guess work by a visit to the vet for a complete physical.  A blood work panel is really the only way to say for sure what is going on inside and is one of the best diagnostic tools for ruling in or out a problem.

Feeding some people food especially fruits and vegetables is ok for dogs.  There are some to avoid though that can be harmful to the kidneys such as grapes or raisens.  Check out our article on dogs and human food for more information.

There are many diseases that dogs get that are very similar to what humans get.  Dogs can get Parkinson's Disease but unlike people where it is an elderly disease, it is seen in young dogs as it is believed to be hereditary. 

I know this can be a difficult time of year to allow for a vet visit in the budget but it is always more settling to know for sure what is or isn't going on with your animal.  If need be, you could ask the vet to take the diagnostics one step at a time and see what information you may get rather than doing several tests all at once.  The visit may take quite a bit longer but you may save some money that way.

I hope this helps and please keep us posted on how Tiny is feeling!
