Hi there,
It is great to ask these questions, because for me...I was a first time dog (even pet!) owner and everything scared me about it because I never knew what was "normal". My sweet vet's team of amazing nurses were so patient with me calling every hour and asking "is this normal"?! Ha. Everything was always normal when I called, I was just so unprepared of what it would be/feel like.
Well, what I was surprised the most about was how quickly Brooklyn wanted to get back to normal activity! We had to keep her calm and quiet. Don't let her jump up (on you, couch, anything) to prevent scar tissue from forming or irritating the wound. The first few days were hard for Brooklyn, she was just a sad whimpering little thing. Make sure the vet gives you pain meds and a back up plan in case she needs something stronger (probably won't, but since this vet is so far away, best to cover all options). We had to end up giving Brooklyn stronger meds for a few days to help with the pain, but she had some tiny complications so that is why. But always good to be safe.
Brooklyn also did not want to eat a thing for a few days or walk to her water bowl. So, to keep nutrients in her, I boiled chicken, scrambled eggs and cooked plain rice and just fed her that little tiny bits (don't want to feed too much the first day or two) at a time throughout the day. I also put her water in a tiny dish and remembered to keep bringing it to her that first day or two before she wanted to move around again. They need to keep their fluids up, but that first day home, she will probably not want to move much, so just bring it to her.
Also, it will be emotional for you (it is hard to see these babies go through any surgery), but remember to keep your energy in check...if you feel confident and strong, Piper will be much more okay and fine with what is going on. It is when we break down and worry that they think "hey, maybe something is wrong". But they are SO resilient and this is such a common surgery, so while it is emotional for us (I know it was for me!), we need to stay confident and normal for our pups to feel secure and okay
Oh, and Brooklyn got the shivers/shakes a bit after her desexing, the vet said it was totally normal after a surgery (over 2 days though, it is not normal) and just to pop a fleece coat/sweater on her. So we kept a fleece coat on her for about a week afterwards which helped.
And as always, since this vet is far away, just have some numbers and locations of vets in the area and any 24 hour vets in the area just in case. Even if you never use these, we should all have our closest vet, closest emergency hospital and closest after hours vet in a place we can easily get to and remember. There is no time for Google in an emergency!! Brooklyn goes to a vet that is a little further away because I just love their practice so much, but in case of a quick acting emergency, I know all my options, day or night
The first night is hard, she will whine and be pretty confused about what has just happened. But get through it because the second night is much better...I promise! Give her some warm blankets and a nice dark place to rest and she will get through. Good luck!!
