Help our rescued street Dogs

A couple of months ago we found two dogs sheltering under our house scared and very skinny! We fed them and gave them some shelter. Before we knew it they became a part of our family and we couldn't bare to give them away. We are a family of four (humans), My wife and a 3 yr old and 6mnths old plus our two dogs rescued dogs "Michael Jackson" and "Thriller" (both female). At the moment things are tight money wise with food, clothing, housing costs and bills, we just cant afford to get the dogs vaccinated, sterilised, chiped (council regulation) and build a nice little house for them (they are living in our laundry). We have never done this before but we, especially the kids love the dogs and we want to give them the best life we can and not have to give them away, so any little donation would be greatly appreciated to help us pay their vet bills.
