one of my rotts did both her cruciates the 2nd went about 6 months after the 1st one, there are a couple of different cruciate operations and the tplo way does normally cost appprox £2500 after 8 weeks crate rest and then taking it easy for a while she was completely back to normal. To watch her now 2 years on you would never know she had it done. Would definately sort out insurance now then return to a different vet.
