Re: Soooo skinny!
All my puppies were at a healthy weight when picked up from the breeder. Little fat, red, wrinkly puppies. Its the only time in their lives that being fat is cute. Yes, worms can cause drastic weight loss, but the pup should have been checked, and wormed before it ever came to seeing ribs and spine. Is your vet checking for worms, or just worming? I would want them to do a stool check before they just keep worming the pup. If the pup doesn't have worms and something else is going on, you need to know.
Pups do go through growth spurts, where they get really lean and leggy. But the spine showing is a severely under weight pup, and could be anemic. Have you looked at his gums? They should be pink, and not white in color.
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.
