My 8 year old res has respiratory infection I believe was caused by neighbors weed blowing over into our yard. In any event I brought him to the vet last Thursday as he was tilted to the right side and not swimming as normal in his outdoor stock tank. He also had not eaten for about a week - even earthworms or chicken which he normally loves. They gave him an injection of ceftazidime280mg and he is supposed to have shots every 3 days for 3 weeks. Now he is getting worse and has lots of bubbles when underwater and still not eating,
My question - is it normal for him to get worse before better? Is this a good antiobiotic? I asked about Baytril as I saw a lot of people on the board used Baytril but she said she wanted to try this first as baytril injections can cause muscle damage? What do others think?
