My name is ***** ***** I’ve been involved professionally with dogs in the health and behavioral fields for over 18 years. It will be my pleasure to work with you today.
Dogs do grieve for lost companions but they also pick up on the feelings of their human companions. The fact that she seemed to be doing ok and suddenly started displaying these symptoms worries me.
She is an elderly dog and when a dog is not eating or drinking, she needs to be seen. It may be due to a disc issue which the breed is prone to that is causing her pain when she lowers her head to eat or drink. It might also be organ failure leading to the loss of appetite. It does sound as if she may be experiencing seizures as well and possibly going into shock as well. Seizures can occur during organ failure. They can also occur when a dog stops eating due to low blood sugar (hypoglycemia). Put a drop of karo or pancake syrup on her gums to help bring her sugar levels up.
I urge you to have her seen as soon as possible. You can read up on organ failure here.
She is likely going to need rehydration if she hasn't been drinking . You can check for dehydration by lifting the skin between the shoulder blades. If it does not snap back down into place fairly quickly then she is dehydrated and need vet care immediately. Tacky gums is another sign of dehydration.
