What's the needle sizes that you used on your bun. I used 25g hub type and the penicillin won't go in, back pressured and splashed All over him and me .I live in CT and I believe the law is that I can only get up to 10 needles without a prescription which my vet will not give me unfortunately, she was very insistant on the every 48 hours and so I was able to do them once a day for the past weeks is beacuse they gave me extras at our first appoinment. I was only given 6 (3 of each size, which would last me 3 days) for this week, which is why I was gonna do it every other day. I not sure if I am legally allowed to purchase needles online unfortunately.
Tried twice and got the same result. He was so scared and peed on me (never like this before).
And just found out that he has fur mites today.
