Puppies are always growing.
If they are hungry, I fed them.
I couldn't tell by the pictures.
If her spine is showing, up her food intake.
You can start by giving her either adding a 1/4 or 1/3 cup more at each meal. Then adjust it by how she looks, or if she starts leaving food in the bowl.
Not all those who wander are lost.
Life is just a leap of faith.
Spread your arms and hold your breath and always trust your cape.
Two things define you. Your patience when you have nothing, and your attitude when you have everything.
