My puppy has these bumps on his tongue not sure what they are or the cause.

I'll bet a vet would know. If you have a standing relationship with one, you could probably email that photo (if they are limiting visits as ours is.)

I’ll suggest you consult a vet before giving your puppy any medicine. Since the country is under lockdown if you already know a vet you can share this pic via email with them. If not, there are a couple of websites where you might find helpful for the same.
Greatvet.com: I’ll personally recommend this one as a couple of weeks ago my cat (munchkin breed) had a severe stomach ache. I actually sent an email to a couple of similar sites, they were the first ones to respond. Thankfully, she’s much better now.

Hope this might be helpful!
