Sudden Change in Behavoir

[Jessika]

When dogs experience an acute change in behavior, its likely because they are in pain, or something is wrong with them. Pets can't come up to us and say, "Hey, my hips been bothering me, do you mind taking me to the vet to see what the problem is?" so they have to get our attention in other ways. Going potty in the house (or out of the litter box, for cats), nipping when you pet them on certain areas of their body, etc.

You say she has hip displaysia and artiritis, this could very well be the culprit. She could be in a "bad" or "grouchy" mood 'cause she isn't feeling well!!

To add to the good advice above it could be pain or having gotten a shock by something and unfortunately she's connected it with you!

If she suddenly experienced a sharp pain in her hip, for example, when you sat down with her then she very well might associate YOU with the pain. I would advise a vet check (which you are already doing ) and then some exercises to associate you with good things... Not forcing her to interact with you but more 'enticing' her

Good luck

I really appreciate everyones input. Thank you.
Katie is doing much better and the medicine she is on for her hips is really helping.
As soon as the pain was somewhat relieved she became more and more normal.
Since she is an older dog with health problems we will enjoy the time we have with her.
I am so glad that she treats me exactly the way she used to.
Again thank all of you for some great advice and understanding
