So we got our little fella yesterday. Giant breed, 10 weeks, weighs barely 8lb. though he's perfectly formed.

He ate and drank happily yesterday afternoon/evening but this morning has had two bouts diarrhoea, will not eat and most importantly wont drink. Hasn't had a drink since bed last night. I've spoon fed him a coupe of mouthfuls of water.

Any advice on how to deal with a small pup with upset tummy?

he's due his 2nd jabs this afternoon, so will see a vet today.

Your Vet will be able to see if all is well.

I would speak to the breeder too to keep them updated. Hope he is OK and its just a case of a change of home. It can upset some pups more than others. But the vet is most important and if he is poorly then its not the best time to have the jabs, wait till he is fit and well.

Regards drinking try getting some bone broth or poach some fish or chicken in water and give him the cooking water. It may get him to drink .otherwise the vet can help with rehydration fluids if needed .totally agree with merlot about jabs. He needs to be fdit and healthy for those.mucj better to delay than give if he is under the weather  .I also endorse speaking g to the breeder so they are aware how he is

I’d be hugely concerned about the weight, my Golden retriever pups are much heavier than this at 8 weeks.  Did the puppy come from a reputable breeder, were the others in the litter as small?

I agree, that is tiny even for my medium breed. Would be a trip to the vet for me if that's accurate. Not eating isn't as much of a worry as not drinking. Vet check.

Hi,

Thanks for so many replies,

He def wont be having jabs today - but will see the vet anyway as the appt was already made.

The others in the litter are twice the size, the breeder is well regarded I think, been breeding for many years and does well showing and the like.  She said she didn't think he would survive as he as was so tiny at birth, but he has thrived since then and hopefully thoroughly checked by her vet before coming to us.

We did know he would be small, though a tad surprised at just how tiny he really is. I don't mind small if he's happy and healthy in life.

He has also started vomiting so really eager to get him to the vet and hopefully treated. At his size/weight cant afford him to be dehydrated. Poor little man.

Pleased to report that pup has significantly improved since yesterday. Vet appt went well, no fever, good heart/lungs and general wellbeing otherwise. She gave him Metacam and naturebio to ease any inflammation in the gut and for the upset tum.

Jabs rebooked for next week

She did say that a significantly small pup is often a sign of some weakness but couldn't find anything to suggest poor health so we are happy with that. :)

Glad he is ok

My breed is only medium with adult bitches 17 - 20kg and height 19 - 20 inches at shoulder. 
I expect my pups to average 10 pounds at 8 weeks with a range of 9 - 12 being usual.

If this is a giant breed I would have serious dounts as to this puppy  being healthy and normal enough to lead a long life.
