Just called the vet Wifi is doing well, the stitches are holding and everything seems like it might heal without amputation. Wifi was fed and ate well 😀 , he was able to pee which is a really good sign . All in all he is in good spirits I will be calling the vet around three to see if I (Alex) can take him home. Because he cannot keep warm by himself I bought him a few sweaters and an extra soft puppy bed. There will be pictures 😉 He will be on a high end speciality diet to fatten him up and will need regular vet care for a while , but we are very optimistic that this little guy will not only pull through but thrive 😉 Once again thank you everyone for helping and sharing.
