Hypoglycemia is important to watch for in small puppies. It is when the blood sugar levels become critically low. This is why it is important to be sure your puppy is eating and taking breaks from play sessions.
What to look for:
- Change in appetite
- Pale gums
- Vomiting clear or bile
If your puppy is acting sluggish due to low blood sugar, a small amount of Karo syrup or honey may help restore the needed sugars. If this does not help it is recommended to seek veterinarian help right away as low blood sugar can be life threatening.
It is recommended to feed your small puppy at least 3-5 times a day, most important being before bed and first thing in the morning. This can help to prevent hypoglycemia. Leaving food down at all times can help as well. Australian Shepherds are active puppies, I have never had a puppy become overweight from food being available at all times.
