Hi my vet's also recommended I had Archie done as soon as he was 6mths old, but he then swallowed the pop sock resulting in major op so I really dont want to have to put him through another lot of surgery just yet. My vet's totally understood and said to re think about it in the summer. Archie is now 8mths on Tues and the vet said he can be done really anytime but best before he is 24mths. What area are you in, maybe speak to other dog owners and ask which vets they use etc, at the end of the day a good recommendation from a few people can help, and don't do anything in haste.
