Thanks –  your information has been very helpful and at end of week 1 we are doing very well — too well and that’s the problem — very active dog not used to being calm and quiet — but doing his best. your articles and information are very helpful.  Surgery was today – he had a TTA and comes home tomorrow.  They say he did well and had 25% tear in the ligament, slight arthritis and did a meniscus release… thanks for the tips – this is a very big learning process  – first time.
