Dog's back legs weak seasonally, trouble walking. Is it allergies?

Thanks for using Petco Pet Education Center, formerly Petcoach! This is possibly due to allergies. It really comes down to figuring out what is causing his allergies so that they can be treated or the specific allergen avoided. A secondary infection is likely and also needs to be addressed. There are many things that can cause allergies though in most cases they can be broken down into 3 big categories: flea, food and environmental allergies. Allergies are usually worked up in a stepwise fashion starting with flea allergies as this is the easiest and cheapest to take care of. If not on a flea preventative, then it would be a good idea to get started on one. If already on one then it would be a good idea to change to something else (there are many new products out in the market). If not improved in 1-3 months then it is time to move on and check for food allergies by switching to a novel diet (new protein and new carbohydrate). If that does not seem to be the issue then you are left out having to check for environmental allergies which require blood and/or skin tests. Allergies can be very frustrating to deal with at first but so rewarding at the end when we are able to treat them effectively! Based on you description of what he has been doing with his hind limbs, I would be more suspicious of something like patellar luxation and possible arthritis as well based on his breed and weight. That is something that can be checked on physical examination. Typically, this is treated medically first to improve comfort though surgery is sometimes needed. Good luck and have a great day!

Hi there and thank you for using Pet Coach to address your concerns. This could very well be related to arthritis of the back legs. The more arthritis develops, the more painful it becomes for dogs to walk. If there is hip dysplasia and this worsens over time, some dogs can appear to walk as if they are drunk with wobbly legs. I would recommend having Athena looked at by a veterinarian so that the appropriate treatment can be recommended. I typically recommend a multi-modal approach and use anti-inflammatory drugs such as Carprofen, pain medications such as Tramadol, Methadone or Gabapentin. Supplements that I would recommend would include Dasuquin with MSM, Adequan injections and Welactin omega 3 fish oil. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns.

Sorry to hear about Dakota's current predicament. Assuming that her two endocrine conditions are well managed, the problem with mobility is likely a separate problem entirely. A myelogram is certainly a decent option for discovering certain abnormalities in the spine, but the best way to rule these out involve a CT Scan or MRI. These are tests that are available only through a specialty hospital in most cases. If she has feeling in all of her limbs, I have doubts that the disease process is of spinal origin however, particularly if this has already been going on for a week. Other causes of lack of mobility are certain infectious diseases (tick borne diseases in particular), traumatic injuries to the spine (fractures to the actual vertebra), severe arthritis, and several different cancerous processes involving the bones and spinal cord. There are also degenerative neurologic conditions that can affected any of the limbs or the brain, ultimately resulting in mobility issues. I tend to lean towards an infectious process or arthritis since there is pain occurring from time to time. I would say that investigating this issue in more detail with your vet would be worth while, with some blood work and a check for tick borne diseases. Hope this helps!

It sounds like what you are describing is weakness. Did your pup have a neurologic exam? What we look for is evidence of pain (although this can sometimes be inconsistent in pets), loss of sensation to the feet (does he fail to flip his foot back over when the top of his foot is placed down?), and presence or absence of reflexes. The results of these tests can help to determine if it's neurologic in origin and what portion of the spinal cord may be affected. Although, it can sometimes be hard to differentiate orthopedic from neurologic disease. Plain xrays of the spine are helpful to rule out any bony abnormalities, and sometimes we can see evidence of narrow disc spaces, but ultimately we cannot see the spinal cord, nerves leaving the spinal cord, or the soft tissues. If a neurologic problem is suspected an MRI is often needed. But, there are also some other conditions that can cause weakness that are metabolic in origin (has your guy had any senior lab work recently?) or related to loss of signaling to the muscles (for example a disease called myasthenia gravis) or related to a degenerative process such as degenerative myelopathy. If there is a component of pain detected on exam then anti-inflammatory pain medication may help. If you feel like things are getting worse it would be a good time to have a re-evaluation with your family vet. Another option as well, if a neurologic process is suspected, would be to have a consult with a veterinary neurologist.

As you said this is probably due to an allergy, although it could also be infection or mites. First of all, in order to rule out skin parasites, you will need to treat with a high quality flea treatment (advocate or advantage), then ask the vet to perform a skin scrape - this might reveal an infection or a mite infestation. If all of those came back negative, the next step is to treat the allergy symptomatically and try to discover the cause of the allergy. Three main type of allergies are usually affecting pets: food allergies, flea and parasite related ones and environmental type (allergens coming from trees, pollens, dust etc etc). Some medications can be given by the vet in order to repair any possible skin lesions (like steroids and antibiotics). Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

Thanks for using Petco Pet Education Center, formerly Petcoach! This is possibly due to allergies. This is quite severe and warrants therapy. The likely secondary infections need to to be addressed and the itchiness also need to be addressed to prevent this issue from getting worse. Medications like prednisone can be used for the itchiness and antibiotics for the infections. In the meantime, you can use an e-collar in the meantime to prevent further self-trauma.

This is most likely from a bulging intervertebral disc pressing on the nerves to his legs. I recommend a veterinary exam and spinal X-ray to be sure. Then as long as he’s walking I recommend pain medication, muscle relaxers and I treat these dogs with laser and acupuncture. He needs to rest, no running or jumping and short slow leash walks for three weeks. Usually this will improve with treatment in three to four weeks. He also could rupture the intervertebral disc and become paralyzed. That is a medical emergency and he may need surgery by a specialist so he could walk again. Please take him in soon and get treatment. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Armor.
