https://www.vetsurgeon.org/f/clinical-questions/25988/dropped-jaw Hi there This client has never had her six chihuahuas vaccinated but reluctantly decided to do so in case something happened to her and they needed to go into kennels. All dog were healthy at the time. However about four weeks later her six year olden-USTelligent Community 10https://www.vetsurgeon.org/thread/181883?ContentTypeID=1Mon, 17 Jul 2017 20:40:55 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:c5048a1a-0e74-42de-8a68-9ba6bb29efdbNiall Taylor<p>[quote user=&quot;dachsie_4&quot;]her six year old only boy developed dropped jaw.

Has she been feeding them Chinese jerky treats or gone mental with the parasite control with her new found enthusiasm for preventative medicine?</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/181857?ContentTypeID=1Mon, 17 Jul 2017 07:50:26 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:133540cb-a745-4e57-8340-a3bb754f58c1Kate Richardson<p>I&#39;m usually one of the first to dismiss the vaccine as causative but this is one I consider more- could the distemper virus cause these symptoms? I have no personal experience of distemper. am thinking parvo or hepatitis virus or lepto less likely But then there&#39;s the liver enzymes (although I wouldn&#39;t read too much into that if mild) and the renal failure. I would contact the manufacturer and report as a suspect adverse reaction, and research further, at the very least it shows you are addressing her concerns seriously. Do keep us posted&nbsp;</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/181856?ContentTypeID=1Mon, 17 Jul 2017 03:15:02 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:7c5f7bcb-6cb2-4e2f-a8d6-301ce18bfd39Chris Milligan<p>Dropped jaw in the absence of other symptoms and if the patient is swallowing normally is almost always due to some form of bilateral trigeminal neuropathy (has to be both sides affected to cause the jaw to drop) though the aetiology isn&#39;t fully understood yet. Immune mediated and infectious causes are likely at play. They typically resolve without any intervention though it can be difficult making the call of course. Some suggest TMj rads to rule out an issue there but if this is affecting multiple dogs you have to be concerned about something infectious or environmental/toxic. I&#39;ve heard of canine herpes causing this syndrome but it&#39;s not usually an older dog issue.&nbsp;</p> <p>A good neurologist might be able to shed more light on the situation - try speaking to one of the university hospitals.</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/181855?ContentTypeID=1Mon, 17 Jul 2017 00:18:13 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:5c6cae86-0eca-416e-a115-650416fb6efdEvelyn Barbour-Hill<p>Not quite my field but; mandibular neuropraxis? I suppose it can happen to a Chihuahua?&nbsp; Have these dogs been carrying heavy (relative to Chihuahua) objects?</p> <p>Was the cause of the renal failure diagnosed?</p><div style="clear:both;"></div>
