Hi. It is very difficult to comment, because clearly I am not fully aware of all the blood results and I am not a vet. I can tell you that a low-blood sugar can indeed cause seizures. In fact, hypoglycaemia in diabetics will almost always cause seizures if the blood sugar falls to an extreme level. I am wondering whether, obviously, your dog is in fact diabetic - the extreme thirst is another common symptom. Has your vet ruled this out?
Sorry ... got interrupted so couldn't finish my post ... it is unusual for a dog to suffer hypoglycaemia as a first sign of diabetes (same as humans), because the ordinary process is for hyperglycaemia to occur (high blood sugar), which is then controlled by tablets or insulin. In effect, failure of the pancreas to produce enough insulin causes the blood sugar to rise, and giving insulin or tablets to force more insulin to be produced, corrects the problem. Hypoglycaemia tends to occur due to the dog being given too much insulin. So, although the production of insulin may be a factor, it is doubtful this is diabetes. It could, however, be something connected with the pancreas.
The fever is an indication of infection. So, pancreatitis might be a first thought, although the symptoms you describe don't fully suggest this.
A urinalysis check of protein leakage can help identify any early kidney failure. Has your vet checked this?
Phenobarbital has many side effects and is a complex drug, but a very effective one in controlling seizures. It is worth reading up on it, just so that you are prepared for the changes you may see in your dog - which, I should add, will last for anything from 2 to 8 weeks, before they should subside.
I think your vet is doing the right things, although a true diagnosis is important. He could be right about the poisoning. Obviously, poisoning can be difficult to assess, particularly if you are not able to supervise your dog 24hrs a day. It is certainly worth considering what your dog is eating (even pet food can become toxic to some dogs), treats given, and any chemicals used in the home or garden, as well as what friends, neighbours and children may be using/giving.
Thank you for commenting:
All of these issues occurred all of a sudden. He has never been sick, although I have to be careful because her chews and eats everything.
I don't know exactly what the lab results came back as. The vet told me that his kidney functions were slightly elevated. I asked if this could be a early symptom of kidney failure, and he told me he didn't think so. He said he believed that the slight elevation was caused by the events that occurred that sent him to the vet.
He told me although he could not rule out poisoning he believed he has some type of epilepsy.
He never had any extreme thirst before the weekends events. Since he has been on the phenobarbital he seems to have extreme thirst, increased urination, and he just always seems tired.
He has only been on the medication since Friday night. The vet believes that the problems listed above is side effects of the phenobarbital.
It's just that I worry so much about these things I cannot fix. I cannot be with him 24hrs per day, I have to work. I will be gad when he adjust to the meds and hopefully these side effects will dissipate.
Hi. It may be useful to note that epilepsy is actually more common amongst Pomeranians. It is one of several breeds that tend to have a higher prevalence of suffering from it. Yes, the side effects will subside, but it will take time. It will be useful for you to keep a diary of daily observations, particularly if you see anything that may indicate there are signs of seizures still occuring. Also, has your vet booked your dog in for his next blood tests?
