This morning I noticed Nelson had this pale green mucus sitting oin top of his penis when I woke up (he was lying on his back still sleeping). I remember I saw it once or twice when he was really little i just thought itd go away. But maybe he gets it every day because every morning when he wakes up i always notice him licking his penis but i always thought "ahh nelson you dirty boy!". but maybe he's been licking this stuff off every morning. should i take him to the vet about it or call the vet? has anyone else noticed this on their puppy? should i be worried? because i kinda am!
