At three months old, my male rottweiler pup developed parvo (even after being vaccinated). He spent six days in ICU and my vets miraculously saved him. He weighed 18 pounds after coming home.
He is now 12 months old and weighs 89 pounds. His grandfather is a large guy and his mother is average. I have not seen his father. Question: Can parvo change the growth rate of a male rottie?
I’m afraid I’m not a veterinarian and so I can’t give a professional answer to this question, and it may be one you would also like to ask your own vet, or an online vet such as you’ll find on my Ask A Vet A Question page.
However, I have had personal experience of a Rottweiler puppy having contracted Parvovirus after being vaccinated (until all puppy vaccinations are completed – 4 sets – are completed there is always a risk, and even full vaccination is no 100% guarantee I’m afraid).
When there’s Parvo in puppies there’s generally a period of slower growth and development in the months directly after the illness, but given time it’s my experience that they do in fact catch up eventually.
I think it may simply be that your Rottweiler pup is still very young (at 12 months he’s still an adolescent pup)… he won’t be considered mature or reach his full adult size until he’s somewhere around 2 years old, possibly as late as 3 years old. He will also get his full height before he reaches his full weight, so for a pretty extended period of time most adolescent Rottweilers look a bit ‘gangly’, awkward and out of proportion. Underweight even at times.
However, as long as you’re feeding him a premium quality puppy food (see my Best Puppy Food page for more on this) and he’s healthy and active, then he should eventually reach his full potential quite nicely.
You can learn more about Rottweiler puppy growth and development on my Rottweiler Puppy Growth Chart page, but do bear in mind that every pup is different and your pup may still have some catching up to do.
I hope this helps, and wish you both all the best. Your Rottweiler is one of the lucky ones to have survived Canine Parvovirus and I hope he has a long, happy healthy life ahead of him.
