Its always a chance u take when sedating an animal or even a person, there is a chance u might not wake up. My grandmother is actually a living example of someone who has reaction to being sedated so we know not to let doctors. However with a pet its hard when something unexplainable happens to them and we loose someone we love dearly. I have not met with the new staff at Dr Lacroix's office yet he and his previous doctors were some of the best I have ever known and I am sorry to loose them, however I dont think that this situation is a reflection of the new owner and staffs ability to care for our loved ones. I am deeply sorry for everyone involved. Also as a bather for a local groomer I recomend you trim your dogs toenails at least once a month to keep them familiar with the process, as well as grooming. If they only get these things a few times a year they are less likely to grow used to the process and act calm and relaxed. This keeps you, your pet and his groomer safe and happy! Good Luch to All
