Okay heres the story, we have an old girl Maltese Terrier (never again) and she has a history of mild epilepsy/reactions to certain foods. Usually they are just mild enough for us to comfort her and the incessant head bobbing and tensing goes away. But this time it's weird, and i've read 348949834 things with every possible key word in google to gather info, but i'm wondering if a few pro's here might know.
Mmmk - i woke up early this morning to find my dog had yacked up some of her food or the contents of her stomach whatever they might be in a few different 'puddles' (oh it was the worst smell i've ever smelt) and so i put her on our bathroom with water, some paper and a soft place to lay down etc etc, then this morning i find her to be okay, but notice shes shaking her head sometimes and foaming at the mouth a little bit - she isn't acting weird other than this and it sounds like a poisoning of some sort, but im just stumped.. it seems mild and hasn't been going for too long but if it continues and she doesn't drink any of her water im thinking i should just take her to the Vet.. but in the meantime anyone know what this could be?
BTW i haven't administered any flea/tick/heartworm medicine recently and haven't been feeding her any different. And we don't live in an area which has toads / poisonous critters for her to eat (cos shes little anyway and wasn't outside last night).
You are very vague in you post, but based on a couple of key things: age of the dog, seizure like symptoms, and vomiting, I'd strongly recommend you go to a veterinarian who does a "geriatric" workup on your dog. This should include a complete physical exam--including looking in the eyes, the ears, listening to the heart and lungs and palpating the abdomen. Second, you didn't give a history, but if your dog has a history of "mild epilepsy" and hasn't had blood work done recently, I'd recommend a CBC, chemistry profile and Urinalysis. The reason being is that in older dogs often don't show overt signs of renal or liver disease intially (diseases which will cause vomiting and seizure like behavior) they can have subtle changes in the urine concentrating ability or chemistry profile. If those tests are normal, then consider other things like a food reaction.
I'd also advise you not listen to Flower. Food allergies rarely present as the seizure like activity you've described in dogs and are much more likely to present as skin or ear inflammation with or without secondary infection and/or GI signs such as soft runny stools or frequent bowel movements. Randomly changing the diet in an older dog with the possibility of underlying medical problems isn't the wisest thing and may result in undue stress on the dog.
Not only that I'd question the veterinarian you took her to if all they did was do a physical exam and tell you its "probably something she ate" in a dog that you describe as not being a chewer or one that could have possibly ingested something toxic. I'd have to see your dog, but I'd be really concerned about "head bobbing behavior" with what you have described as a history of "mild epilepsy" and one who is vomiting. That is not a history or clinical sign to be taken lightly in an older dog in my opinion.
