Thought I would chime in...I have spayed all 4 of my girls, all within their first yr of life. Never had any issues with fur growth, but I live in colder climates. One thing I have always had was fur abundance. Last year was a BAD winter here. My girls coated up like CRAZY they really packed on the undercoat to deal with the (-) temps we got early on. They all came from furry parents though-working dogs. I have recently dealt with spay incontinence in Savannah. She is smaller-15 lbs. Nap time and overnight she was having trouble holding urine, no dripping between, just when she went into a deeper sleep she had issues. She will be 3 on labor day, so kinda early for this. Consulting the Vets-I go the holistic route-I use meds as the last avenue if possible. We found what worked for her and she is dry again-no further issues. This has been over the summer. I have wondered if the heat(it happened once it was getting so incredibly hot here) and the increased water intake to deal with the heat has been a factor-who knows. Kaleigh & Savannah were spayed at almost 7 mths. Kaleigh is bigger by about 5 to 7 lbs. Both done by the same Dr., both woke up shortly from the surgery and wanted to come home. Both recovered quickly and sutures dissolved fast. I was a basket case both times, but they did great-no issues. I had used country Vets in the past, on my previous two girls. Kaleigh was seeing a holistic Vet who didn't perform surgeries. Finding a Vet that would perform the surgery w/o an overnight stay, w/o trying to revaccinate Kaleigh was near impossible. Classic ego power struggle for the clinics that didn't recognize holistic Vets. Holistic Vets use the SAME vaccinations as they do, from the SAME sources, as required by the state, they just don't always administer them ALL together, and they dose per weight of the dog which some of the clinics do not. They have to be certified and licensed by the State-so it was ridiculous. My breeder uses a country Vet and they gave me loads of grief about that as well. The breeder, the country Vet, and my holistic Vet all backed me up against the clinics trying to force re-vaccination on Kaleigh to spay her. The claim/excuse was she might not be healthy or pose risk and they needed to be sure. Which was INSANE. We had health records on her parents, health records on her, everything was documented. VERY sore subject for me, because the clinics in my area were nothing more than profit makers, it isn't about true health of a pet, it is about price GOUGING, and padding the bottom line as much as possible for services. Which I proved to the state from the estimates I got from these places. Just because I wasn't using their "preferred" Vets or their vaccination recommendations, etc. I mention all that to say, comparison shop, know the attitudes and procedures of any clinic you use, and make SURE you know what they will charge for, what they will be doing before, during and after any procedure. Make sure it aligns with your personal choices. Question everything so you feel comfortable and confident. Get it in writing, especially the costs. I learned a lot about the process with Kaleigh-times had really changed from what I was use to, and I will say NOT for the better imho. My previous girls never were put through the wringer on a routine spay like what I dealt with for her. My dogs have all lived long happy lives being spayed. We had girl dogs growing up that were spayed. None had their first cycle, or a litter. I suspect Kaleigh & Savannah will age out as well. Savannah is petite, she is finer boned than any of my others, and I think a bit more sensitive healthwise due to her size. With anything, do what FEELS right for your circumstance. Find a Vet that answers all your concerns.
