You might want to try switching him over to a higher quality puppy food. If you can buy it at the grocery store, it's usually not a very high quality diet and is full of fillers and other things that might not be as beneficial.

These tiny dogs are prone to hypoglycemia when they don't eat or drink for a couple of days or when they are ill. They can also become anemic easily and have othe problems. This can cause stumbling and other neurological symptoms.

I would suggest that you purchase a high quality dry food in small bites that you can leave out all the time. These little dogs usually won't eat it unless it's in small bites. Iams is great and I like eukanuba. Just be sure that it's small bites. Leave a few tablespoons out for him all the time and "free feed." He might only eat a few bites each day but it's there if he wants it. I would then offer him a quality canned food twice a day. Leave it out for 30 minutes and then take it back up. If he does not eat it, start again with the next feeding. Don't leave it out for more than 30 minutes.

With these little dogs, you can never give them treats or table food until they get a little older. If you ever give it, they will wait for it and won't eat until they get it.

These little dogs will win out because of the low blood sugar problems if you let them. You can somewhat combat this by giving the dog neutracal a few times a day. It's a paste that is loaded with vitamins and keep his blood sugar up. It sounds like you are already familiar with it.

As he gets a little older, you can be a little more free with his food. You just need to get him through this rough spot.

I hope this helps!

If you still have specific questions, feel free to ask.

There are some simple things you can do if your dog might be suffering from allergies.

I would talk with the vet about a different low allergy diet, one that will have the least reaction. Rabbit and potato is good, but you can choose another brand. Try steering clear of brands that have corn.

You should also get her on a flea preventative if she is not already. Even if you don't see fleas, it only takes one to get the cycle started. Some dogs are highly allergic to flea bites.

I would also use a prescribed dose of benadryl, especially during allergy season. My vet recommends 1 mg per lb of body weight given every 8-12 hours.

Keep in mind that dogs can have allergies to pollen, dust and other household allergens so you should evaluate your home and try to make it as allergy free as you possibly can for her.

It sounds like the dog might also have a secondary bacterial or fungal infection. This is usually secondary to allergies and itching. This means that the secondary problem is caused by the primary.

When dogs scratch, they abrade the skin and allow bacterial and funguses to enter the skin. The result is a bacterial or fungal infection. This is what causes a smell. This is probably why the vet prescribed antibiotics.

If this continues, you need to see the vet so that they can get a culture and tell you what kind of treatment is necessary.

While you are there, you should also speak with the vet about a supplement that has omega three fatty acids. Good skin starts from the inside out and this can be very beneficial.

Thyroid conditions can also cause hair loss so you will want to see the vet to rule this out if the condition persists.

Let me know if you still have questions.
