My name is***** and I can help you tonight. I am really sorry to hear that Aggie is having seizures. What specific questions do you have?
Okay. Great. So her primary problems are weight gain and seizures?
Possible causes of weight gain include-
-too much food
Possible causes of seizures include-
-epilepsy (but weird to see late age onset)
-meningitis (immune system problem)
Possible causes of heavy panting-
-Pain (in her head or other places)
Possible causes of slobbering-
-difficulty swallowing (is she having any trouble eating or drinking?)
-nerve problems in the back of the throat area
If I was to put all of her symptoms into one or two diagnoses- I would consider hypothyroidism or a brain tumor as my first thoughts.
I was typing, sorry.
Blood work to look for thyroid disease and Cushing's would be the first steps to take to ensure there is no metabolic problem to consider.
The next step would be a referral to a veterinary neurologist for a neurologic exam. They will likely recommend an MRI of her head and if that suggests a CSF tap (fluid around the brain collection) then they can do that too.
I suggested a brain tumor because she is an old Frenchie. The most common causes of seizures in old dogs is a brain tumor and these are even more common in Frenchies, unfortunately.
Here is a link about dog seizures-
The link talks a lot about using phenobarbital for seizure control. Very few veterinarians are using this drug anymore, there are better choices, like Keppra and Zonisemide.
The slobbering worries me because that means that she can't swallow her saliva properly. I would watch her very closely when she is eating and drinking as well and see if she is having problems with these activities as well. Picking up food, putting it in the back of the throat and swallowing it are all controlled by cranial nerves 9, 10, and 11 (at the base of the brain stem). If there is a tumor on her brain stem, this would affect swallowing.
I don't know if I could put that together with the other things, but low thyroid can cause weird intestinal signs.
I am going off-line for about 45 minutes to eat dinner with my family, but I will be back to chat more if you have any more questions.
I hope all of this helps so far.
Okay. I'm back. What questions do you have?
How is Aggie tonight? Any more seizures? Were you able to watch her eat? Was she having any problems?
Please let me know how she is doing? I was worried about her today.
