Tramadol is very strong and seems to be the pain relief of choice for dogs these days, in humans we would start off with Paracetamol[not for dogs as the liver can't cope with it], then add in codeine [ not sure if dogs can process this OK]in increasing doses and when those no longer worked then something like Tramadol would be tried, I can remember trialing this on my patients with Rheumatoid Arthritis back in the mid 90's so it hasn't been around that long and filled the gap between the simple painkillers and the Morphine type meds.
I was on Tramadol for several years and like any strong pain meds you feel sleepy till you get used to them and eventually they stop working as the condition you are taking them for gets worse, I didn't have any withdrawal symptoms, not even when I was going into hospital for surgery and had to fast from the night before and take no meds either, back in 2006 I went on to Morphine after fighting against that option for several years and now have a patch with a drug equivalent to Morphine which lasts 3 days.
Like all meds there will be some folk that it won't agree with but I have only come across a couple.
If the specialist didn't like Tramadol for dogs I would have liked to know what other meds they would have suggested other than anti inflammatories.
