I'm sorry that I was offline when you asked your question about your 17 year old dog; I'm also sorry to hear about her recent injury.
Do you still require assistance? If so, I'd be more than happy to address your questions.
1. Yes, Carprofen can help with inflammation since it's a non-steroidal anti-inflammatory drug; however, I typically dose at twice a day...1 mg/lb of body weight.. although it can be dosed at once a day (2 mg/lb).
2. 100 mg once a day or 50 mg twice a day is the dose I'd suggest for a 61 lb dog.
3. I would help lift her with a towel or sling wrapped around her midsection since she may inadvertently reinjure herself. I wouldn't let her struggle to stand although if she's just shifting her body weight while on the floor, she may not need your help to do so.
4. I doubt it unless she fell off the ramp which doesn't sound like the case. I would imagine that in her current state that it would be difficult for her to make it up the ramp, though, without your helping her which shouldn't cause more damage.
5. I would expect her to recover with time and that irreversible damage wasn't done; however, as you no doubt know, compression of the cord by a disc may also be responsible for her signs. It's also possible, given her age, that she has other issues which are complicating the situation such as arthritis and possible decreased muscle tone.
6. Concurrent use of Carprofen and steroids is contraindicated since gastric ulceration is a risk when both are given together. It's just not something which is recommended. And when changing from one to the other, there should be a wash-out period of 3-5 days which wouldn't be wise in this situation. If your vet was going to use steroids, they should have done so at the outset as soon as she injured herself.
Having said that, though, the authors of one study reported that 79% of 38 dogs with disc-related lumbosacral disease treated with epidural administration of methylprednisolone acetate (a steroid) demonstrated clinical improvement. Treatment consisted of three injections given approximately 2 and 6 weeks following the first injection.
I'm not sure how wise this would be at this point but it may be something to consider if she's not showing signs of improvement on her current medications.
7. I think that acupuncture may be of benefit but I don't have personal experience with any patients who have had this done for this particular problem. I wouldn't expect it to interfere of cause issues at the tumor removal site.
8. I think laser therapy can play a role in these patients as well and often suggest it for many of my patients with various orthopedic/neurologic conditions. I have to refer them, though, since we don't offer this service at my hospital.
9. I don't think warm compresses would necessarily be harmful but I don't know how much benefit they'd be at this point. Certainly worth trying, though.
10. Cold packs are generally suggested within the first 72 hours of an injury so I'd use warm compresses if anything.
11. Definitely worthwhile if you have a vet who makes house calls in your area. Given the difficulty in getting her to the vet's office and the injury she sustained there, treatment at home would be far preferable.
12. You should continue to be her advocate as long as her quality of life is good...which is sounds like it primarily is. I would give her every opportunity to respond to rest and medication. If she were my patient, I'd increase her Tramadol dose to probably 100 mg 2-3 times a day; her current dose of 50 mg/ day is low.
I might also add Gabapentin (another pain medication which works better than Tramadol for neuropathic pain) as well. All three drugs can be given together and most patients tolerate this combination quite well.
I don't know if Adequan would be helpful for her lumbosacral disease but this may be something else to consider especially if she has osteoarthritis somewhere in her body which is complicating her situation. It's an injection which would have to be given twice weekly by a vet (hopefully one who makes housecalls) and then once per month.
I'd also start her on a combinations of antioxidants such as Cell Advance 880 or Golden Years as well as Tumeric 1000mg/day.
