my dogs is almost 4 years now.
i have applied flea control product about 4 or 5 weeks ago.
Spots are dark brown or light black. no red spots.
One spot is very small size of peanuts. it has appered about 3weeks ago and today i have found another spot. It size of ...um... half of redit card?.. haha but its round spot.
I am not sure about the products name.
my grommer did applied flea control product. i think she called first line but not sure.
These black spots are not rough to touch...just like people birth marks...(i guess).
they are flat and smooth. i didn't notice till i gave her bath today.
But it still hard find why. yout answer was too wide for me. i still have no clue.
based on your answer, i think it's food allergy but...i am not positive.
The spots are on her back. i am not sure the spots are itchy. She can't reach it anyways. But her legs and face or ears seems itchy. Because she rubs her face on carpet and bites her legs. She doesn't have red ears or smally skin.
