I have one that is smaller and one larger, full grown. The only difference I have ever noticed is the smaller one, Lacey, when a puppy, tended to get hypoglycemic when she was tired or overwrought, so I kept Nutrical handy. She is still more delicate in her features and weighs under 4 lbs but is as hardy as Chloe, who is getting a little porky at 7 lbs, needs to eat less or exercise more. Both are very healthy but I do have to protect Lacey a little bit more, or at least consider more things, like will she get cold when I bathe her, etc. |
