My puppy has white spots on nails. Is it a calcium deficiency?

Congratulations on your new puppy! This white coloration is not anything I would be concerned about if the nails are otherwise normal. We do worry if the nails begin to turn brown/rust colored or if the nails become brittle/painful, these could be signs of different disease processes, but the white areas are a normal variation.

These white spots can be normal color variation on the nails. The deep pink/red color within the nails is from where the blood and nerve supply run down the nail. This is also known as the quick of the nails and should be avoided when trimming their nails. From the photo, your puppy's nails appear normal. If you see a dark brown color on the surface of the nails near the nail beds, this can indicate a yeast infection but this is not seen in the photo provided. Have fun with your new puppy.

Not necessarily, but without seeing Max in person, I can't say for certain. Be sure you are feeding him a high quality puppy food, which will give him all the calcium he needs. I'd also have this checked out by a vet. Best of luck.

If he walks on concrete or a hard surface then he may be wearing them down on his own, especially if the nails look normal. You could have your vet take a look at his nails if you are concerned there is a problem.

Those lesions could indicate a fungus but it could also indicate a previous split nail that is not healing properly. I recommend to have Fiona examined by the veterinarian to have this addressed. Split nails generally need to be clipped behind the break so they grow out properly. I hope this helps.

The nail different color is probably normal, it is very common. regarding the hair it is recommended not to have your dog groomed until the age of 6 months, the reason is they lose their puppy coat at this age and start growing their permanent hair, having them groomed prior to this will often result in what you have experienced. in most cases though it will eventually resolve after the age of 6 months.

I don’t think that the spot in the picture looks like a bruise. To me it looks like maybe a spit of yeast overgrowth. It can cause some itchiness and licking, which makes it grow even faster. You can try bathing the affected areas with a medicated shampoo, like the one linked below. Do this three times a week for a couple weeks. If it seems to increase, affect more toes, you see more licking, etc I would see a vet for more specific treatment.
