what to do?

so we basicly own three dogs. and only two are getting spoiled. one is mine i've had him for about 3 1/2 years already and he goes everywhere with me you name it he's been there as well as getting all those yummy dog treats and food. and then my grandparents own the other two a yorkie and a yorkie/chihuahua mix. so they spoil the yorkie got her three outfits to wear and bought a big bed for her and give her table scraps and such while the mix is jumping for attention all the time they hardly give him any. he owns one thrift store boughten sweater. we occaonaly bring him with us when we go places but my grandparents don't like us doing that so we can hardly do it. but my mother loves him so much and has said numerous times she would love to take him in but they refuse. so the yorkie gave birth to him and two other pups which now have homes. but it was my dog who got her pregnant and as soon as i found out out she was pregant i researched all that i could to the proper care for her and the puppys and even learned of the knot that gets them pregant for sure becasue i caught them in the act and soon learned through 3 days of research that she was in fact pregnant and what do you know she did gave birth to three pups but for some reason my whole family was insistant that i don't get a puppy? it was my dog that got her pregnant but after months of arguing we finally let it go and so each my aunts got a pup and my grandparents kept one. i took all the proper care of her and told everone she is pregnant and to be carfull on what they feed her and all the works. for about the first month or so they did not believe me they said i was lying and such. but as soon as they saw her getting fat they all started discussing which one they wanted. they where all like i should get one because i have been wanting one and what not i said that i would too take one in and they blew up about it and said no way arguing continuesly with my mother that we had enough animals. we own two cats a turtle and my dog and everyone in my family know they are all spoiled profundly even my turtle he gets his island and tank cleaned weakly and fish his favorite snack. but in the end they all took one and they where gone. but even though they where insistant i still helped the puppys out giving them medicine and helping them switch from the mothers milk to soft food then to regular food. but even with them all wining a pup they all hardly pay any attention to them. my aunts pup is put side and has a mess near by him and she is not allowed inside. when ever i vist i clean her area up put clean water for her and take her a shower and pick off the fleas. my other aunt though lost her puppy. and the one kept here as well is neglected i was him take him walking and clip his nails and clean his ears. the same treatment goes to my dog he get his fur washed,nails cliped,ears cleaned,teeth brushed, walked and gets to wear one of his many sweaters and coats. i have tried talking my grandparents into letting us have him but they refuse and i'm not sure what to do for him now. they are always talking of selling him which i feel would be for the better but he absoultly loves my dog. he follows him everywhere and cries if left alone and plus he is unsocialized he barks at everthing and tries to bite strangers which i would not want to give that kind of dog to anyone. but none the less we love him he is cute. still they just won't let if go and not give him up. are there any suggjestions on what i should do? shold i just maybe turn a blind eye to this i do have my own dog to tend to and they are always unhappy with me paying attention to there dog so i'm unsure what to do?
