I would say that's it's probably all to do with the sciatic nerve.
This runs down the past the bum and leg, as in a person.
The reason I say this is, that Mick, my Labrador is having trouble with his back legs, he's 12.
Because he has started "knuckling" sometimes, the vet told me that the messages are not getting through from his brain, down to the sciatic nerve.
His brain is ok, (so don't panic about your dog) nothing wrong with that, it's the nerve where the messages are not getting through.
Mick has been taken off the Metacam and put on some tablets now, they're called "prednoleucotrophin PLT" .
I have been given 14 days worth.
I decided to opt for this, because although Mick is 12, he's healthly and lively in every other way, I want to help him as much as I can to keep him with me, but not to his detriment.
I felt it only fair to him, to give it a try and after the 14 days, I will take him back to the vet, so see if we carry on with them or go back to the Metacam.
The reason I've told you about Mick, is that it sounds the same time of thing, as you mention messages not getting through.
Hope this info helps a bit.
This is what is says on the web:
PLT Tablets are indicated for the treatment of osteoarthritis in the dog.
Dosage and administration
Recommended dosage is based on 25 mg cinchophen/kg bodyweight and 0.125 mg prednisolone/kg bodyweight. This equates to a dose of:
Dogs: 8 kg ½ tablet twice daily
16 kg 1 tablet twice daily
24 kg 1½ tablets twice daily
32 kg and over 2 tablets twice daily
The dose should be administered with food.
The length of treatment with PLT Tablets depends on the condition treated and the rapidity of response. If there is no improvement within the first 3 days, the dog should be re-examined by the veterinary surgeon. However, an initial treatment period should not exceed 14 days after which the dog's condition should be re-assessed by a veterinary surgeon and a 14 day treatment-free interval must be observed before continuing with further treatment. During a course of treatment the situation should be reviewed frequently by close veterinary supervision.
Owing to the prednisolone content, at the end of a treatment period, dose levels should be reduced gradually.
Contra-indications, warnings, etc
Not for use in any animal species other than the dog.
Not to be used in animals with the following conditions: Pregnancy, severe nephrosis, circulatory congestive conditions, hepatitis, previous adverse reaction to a steroid or NSAID treatment, concurrent diuretic therapy or treatment with other NSAIDs or steroids.
Systemic corticosteroid therapy is generally contra-indicated in patients with renal disease and diabetes mellitus. Should any treated animal show signs of vomiting, diarrhea, dullness or jaundice, or show no evidence of improvement after 3 days of treatment, discontinue therapy.
Anti-inflammatory corticosteroids, such as prednisolone, are known to exert a wide range of side-effects. Whilst single high doses are generally well tolerated, they may induce severe side-effects in long term use and when esters possessing a long duration of action are administered. Dosage in medium to long term use should generally be kept to the minimum necessary to control symptoms.
Steroids themselves, during treatment, may cause Cushingoid symptoms involving significant alteration of fat, carbohydrate, protein and mineral metabolism, e.g. redistribution of body fat, muscle weakness and wastage and osteoporosis may result. During therapy effective doses suppress the Hypothalamo-Pituitreal-Adrenal axis. Following cessation of treatment, symptoms of adrenal insufficiency extending to adrenocorticol atrophy can arise and this may render the animal unable to deal adequately with stressful situations. Consideration should therefore be given to means of minimising problems of adrenal insufficiency following the withdrawal of treatment, e.g. a gradual reduction of dosage (for further discussion see standard texts).
Systemically administered corticosteroids may cause polyuria, polydipsia and polyphagia, particularly during the early stages of therapy. Some corticosteroids may cause sodium and water retention and hypokalaemia in long term use. Systemic corticosteroids have caused deposition of calcium in the skin (calcinosis cutis).
Corticosteroids may delay wound healing and the immunosuppressant actions may weaken resistance to, or exacerbate existing infections. In the presence of bacterial infection, anti-bacterial drug cover is usually required when steroids are used. In the presence of viral infections, steroids may worsen or hasten the progress of the disease.
Gastro-intestinal ulceration has been reported in animals treated with corticosteroids and g.i.t. ulceration may be exacerbated by steroids in patients given non-steroidal anti-inflammatory drugs and in corticosteroid treated animals with spinal cord trauma. Steroids may cause enlargement of the liver (hepatomegaly) with increased serum hepatic enzymes.
Gastro-intestinal upsets have been reported. Should inappetance or vomiting occur, medication should be discontinued and the dog re-examined by a veterinary surgeon.
For animal treatment only.
