Hi
OK - diet first. Chappie is not really good enough to raise a dane puppy on I'm afraid - so, you need to get her on something like the following:
Breakfast:
Scrambled eggs
Lunch:
A good quality dry food - I have mine on Burns Complete Vennison and Rice. Its an excellent food, they deliver to the door, It soaks well and is a good protein level.
Burns.
Drink of goats milk
Vitamin C tablet
Dinner:
Tripe. Raw Tripe. Preferably green, with a handful of Burns as a mixer
Supper:
Burns again - soaked.
In a few months time you can drop the supper, and mix the scrambled egg with some Burns. You don't want to over feed her...she needs small amounts often :)
As an adult, she will need two meals a day. Mine have a big bowlful of Burns for breakfast and Tripe and a mixer for dinner. She will need a raised bowl for water and for food. You can see my danes if you click on my profile and then on my site :)
I will ask Grace to pop along and talk to you about the deafness/genetic/colour issue
