Great checkup
Okay so you asked for opinion and these are just my opinion..take em or leave them..
1. Science Diet Food - No/lots of threads on good food- depending which one but to much grain or artifical colors/preservativesIMHO.
2. Micro-chip (ouch - big needle) is best done when being neutered and having baby teeth checked
3. Testicle might never drop so when they do his neuter they will have to open him up a little more..not the end of the world but your vet is right to watch
4. I am not a groomer but I do groom the 10 of mine and I don't understand the powder? I don't use it.
I bet the vet also said you had one special little dog
