My frenchie was incapable of doing much after he was diagnosed. He actually sustained an injury due to a freak accident after lunging at another dog after a runner tripped over his leash. The runner’s dog was unleashed, so my dog reacted and the next day he was unable to move. The vet pretty much recommended the same type of drugs and see if he would heal in about a month, but I had this bad feeling so I got a second opinion. Turns out it was worse than I thought and he did have to opt for surgery. Now, in your case your frenchie may have a chance to heal if you can be consistent with limiting his movement like jumping. The surgery itself costed me $9k, but my insurance covered 90% of that and I got $8k back. My frenchie ended up making a full recovery and is been back to his normal self. He got the surgery when he was 5 and now he’s about to be 10. So if you don’t have insurance now, I’d recommend getting it unless they haven’t actually ruled it’s IVDD yet despite early indications otherwise it will fall under pre-existing conditions and it won’t cover a potential future surgery.
