I have an american staffordshire mix with IBD so i have experiance taking care of health issues/older dogs. On daily oral meds and b12 injections once a week. Ive also had to administer fluids when she gets really sick. Ive house sat for my aunts dogs on and off for the past 8 years or so. Ranging between her older now passed dogs to the newer puppies. I have a 7 month old austrailian cattle dog mix as well.
