Hello. Welcome to Tripawds!!! My Great Dane Valentina did have lots of swelling in her remaining front leg and her paw. Somedays it was gigantic. It looked like someone blew up her foot with air or something like the Nutty Professor lol. The swelling lasted for a lot longer than I thought it would. I believe it was about a month. Being that she was such a large Dog the vet said that it would take longer because the space left behind after the amputation is so big that it accumulates alot of fluid and it has nowhere else to go. Extra fluid usually goes downhill to the extremities. Also I noticed that her leg kind of hung off of the edge of her bed when she was sleeping and I wondered if the angle caused the fluid to go that way. She never acted like her foot bothered her and it eventually went away. The weird thing was after it had gone away and she was mostly healed it swelled up again. The vet gave me some antibiotic spray to put on her foot and between her pads and toes. Within 24 hours the swelling started to go down. The vet thought she may have had a skin infection. She had a very slight rash on the underside of her foot. I think it was getting rubbed raw somewhat from getting used so much in a different way and then got an infection. The swelling looked exactly the same as it did initially when she was recovering from the amputation so it was confusing. With the spray the swelling went away but then came back a second time a while later. We treated it with the same spray again and it went away quickly and never returned. So I'm not sure if the swelling at first was from the amputation or an infection. But I really do think that alot of Dogs do have this kind of swelling in their remaining foot and or leg(s) and it is completely normal. Most likely in Mia's case it is just extra fluid that has nowhere to go so it is going to her remaining front foot. Being that it is still very early in her recovery it does really sound like that's what it is. It will probably be at it's worst for the first couple of weeks and then slowly start to dissipate over the next week or so after that. Just keep an eye on the underside of her foot and the pads of her feet and even between her toes for any redness or rash that could indicate an infection. And of course call your vet if you are not sure if it is normal or not. Especially if the swelling is ongoing after the first few weeks or it goes away and returns. Good Luck with Mia's recovery! She is a beautiful Dog!!
