Thanks all for your comments, especially such a comprehensive view from hcm1.
The wound did get "Surgical debridement", though that term was not used. It wasn't an old wound, nor obviously infected and we hadn't yet given it a chance to heal on its own; but it didn't look likely to me, so I decided to not take the chance and opted for the treatment with the best chance of a cleaner, faster recovery.
I'm not sure that saying we should have discussed fees is helpful though. I have no knowledge to challenge with, and just had to trust the vet that the £600 -800 estimate for treatment was accurate, applicable and reasonable.
It was only when I checked my records later that I was surprised to find that the same practice speyed her 18 months ago for only £345. I'd forgotten that. I assume that the theatre costs for both ops should be comparable, if not more for the speying?
The invoice is very detailed, down to every scalpel blade, swab, glove and apron. But the one line "1 X Suture wound £636.57" seems to do most of the heavy lifting.
I am sorry if I have caused any offence by suggesting that one discusses fees beforehand, that was not aimed at you personally in the least and is obviously zero help to you now! I was meerly suggesting it for others who may be reading this thread. Likewise, fair play to you for seeking attention for your dog the healing should be much faster with this approach. Though for reference I have seen many wounds like that and worse heal with minimal intervention albeit taking much longer. Please do not take this as a carte blanche to never have a wound sutured, or checked by a vet, some seemingly small wounds can involve deeper structures and be quite serious but all I'm saying is that not all small wounds need suturing. For context, a wound only needs to be 6-12 hours old to be considered "surgically old" by this time the body has decided that the edges wont come together so the blood supply retracts from the wound edges and the very edges of the cut start to die back to close the body to infection. To over come this the edges need to be cut back and the process "reset"
Those who have highlighted the involvement of venture capital are very sadly correct, you are in many cases not paying the vets/immediate staff, but rather shareholders. I am fortunate to work in a semi-rural independent practice and as such I only answer to my boss the owner and have the ability to discuss what is charged. for context to have your dog spayed here would cost (for a lab size) approx £220 all in. Just as a point of reference, routine neutering is generally charged out waaay below its surgical value as a loss leader but also to help encourage neutering and reduce unwanted pregnancies and pyometritis in older bitches. I personally would rather suture the most ragged wound you can imagine than spay a bitch, it can be a horribly stressful procedure with a great many risks.
That wound, I would have given you the options of managing at home with bandages etc or to go with a full GA and stitch, I would have explained the costs/risks/benefits and asked you what you would like to do.
Now this approach is based on coming up 14 years of doing the job and 37 years on this earth. when I was a new grad I would have always gone with gold standard regardless, partly because I didn't have the benefit of having seen wounds like this heal just fine but also it was for fear of people complaining I had not done the right job. If you go with gold standard, you cant be accused of doing a poor clinical job!
People are very quick to go with the cheaper option but not so quick to take responsibility for the consequences of THEIR CHOICE of said cheaper option. Nowadays I treat people as responsible adults. If society deems people capable to vote, smoke, drink and self identify then I don't think it is unreasonable to expect people to also make informed (this is key) decisions as regards their pets. Now it up to me to offer guidance and answer questions and help people to come to a decision they are happy with but the ability to do this comes with experience.
I have lost count of the times i have been asked "what would you do if it was yours" sadly, this very often translates into "I don't want the responsibility of making a decision, tell me what to do so i can blame you if it goes wrong" Am I jaded, yes, does it come from experience, also yes!
In your situation pob, you have my sympathies, you have very responsibly done the best for your dog and I am sorry it has cost you so much. It was however the best clinical option, not the only one, but likely the best.
