My dog is lethargic. He hasn't moved for days. Hes gone outside to urinate once today. He goes back to the same spot to lay down. I gave him water and ice cubes, he drank and ate them. He ate a hot dog. He got into the trash a few days ago and I gave him a bath a few days ago also. During the bath I brushed him a lot to get out all of the hairs he's been shedding. I think I may have overbrushed around his neck. there are two patches on either side of his neck that are really red under his coat and seem to be weeping because the fur is slightly damp and hard at the end. I put on an antimicrobial cream for dogs that I got over the counter. It seemed to make it less sore. He wimpers when you go to touch the area. He also has the shivers, when I put a heater by him they went away, but they return when the heater is off. We cannot afford to take him to the vet. He is a lab and 3 years old. He is overweight and has lost some weight over the past few days. We just got him a month ago from the previous owner. Please help.
