Long-term anti-inflammatory injections for dogs will reduce their immunity, cause imbalance in intestinal flora, and develop drug resistance, so dogs cannot be given long-term anti-inflammatory injections. Moreover, dogs will experience increased urination, thirst, fever, etc. after receiving anti-inflammatory injections, so they need to drink more water to avoid dehydration. If your dog has inflammation, it is best to go to the hospital for a check-up to see whether he should get an anti-inflammatory shot or take anti-inflammatory drugs.
