I think You are right to feel so strongly about this-obviously this girl aa you know her is an immature 22 year old and is simply getting a dog because her friends are. I would be angry too. If she is all about 'what's in' then she is not in the right state of mind in getting a dog, and even if she does keep it-what kind of life is it going to have. I say this because when i was 26 i decided to get myself an English pointer! yes a very boisterous dog, needing a lot of exercise1 Then a month later i thought i would get another one for the first one-so at 26 here i was with 2 English pointers and renting! Well Mary and Thomas (my dogs) went through hell with me hiding them from real estates inspecting my home, getting evicted every 6 months cos of the dog hair and smell, going through boyfriends and family issues so me being upset and angry with so much in my life and the poor dogs had to endure me like this. Having said that-they are now 13 and i still have them, i love them to death and even now i own my own house on property, they still sleep under the doona's by the way, i still think i made the wrong decision-for them-they could have went to a better home-maybe or maybe not. Its hard to do butthis girl has to realise that ownership of a dog is at least a 15 year commitment. The best advice that i would recommend is wash your hands of her-for always-forget that its family-family is what you make it-blood is not alwyas thicker than water. Another option is to show her some websites where she could adaopt a very loving shelter dog, or even an older dog-like a little 110 year old dog-show her what people dump at least-that's the best you can do-show her what people dump-i am guessing though that she is not emotionally mature to understand it.
