You did good in saving your boy. He is small and you need to make sure he eats often. Don't just have the food in with him....make sure he eats at least 4 meals a day, with one being at bedtime.
Once they've had an episode, it's easy for them to repeat it...especially in the first few days following. They don't recover 100% for some time and you may want to give him a small amount of Nutrical a couple times a day for the next few days.
Besides making sure he eats, also limit his playtime. Such a small puppy has so little reserves that he can easily over-exert himself. He needs his rest.
If you have another episode, you can use karo syrup or Nutrical to get his sugar up. I use karo as it is supposed to get in the bloodstream faster than Nutrical and time is important. Always follow up by giving him some protein. The sugar helps them recover but isn't meant to sustain them. |
