Omega-3 Improves Your Pet Health

My cat is a 5 yr old female. She has many problematic symptoms and I have taken her to different vets numerous times, without any relief. I’ve been told she had an ear infection, a yeast infection, ear mites, leukemia (which was ruled out), intestinal problems, and digestive problems. Each time I treated her with what was prescribed.
She still has many symptoms such as:
watery eyes
dark spots in her ears
gooey substance in ears
appears to be what looks like scabs on her chin
sleeping more than usual
not as friendly; irritable; sad
vomiting
hair loss
rubbing sides of her face against things
have found stool other than inside litter box (unusual for her)
If any one can please help me in finding possible diagnoses, treatments, causes, information, products, etc…
She is my best buddy, I love her, and I hate to see her like this because it is my responsibility to take good care of her.
Thank you

About 3 days ago I noticed my dogs breath was very bad. I went to Zheres and bought some dog tooth paste and a dog tooth brush, Not the finger one. My dog is a small Bichon Frise, who has never had any health problems. He is 4 years old in septemer this year. His front 4 teeth, are almost exposed and his gums look like (they have been eaten away)… I’ve been brushing his teethe 3 Times a day for the past 4 days. I will continues to do so, and contact my vet on tuesday after the long weekend. what could the disease / infecion be? The top of his teeth, look very dark (like they have some sort of build up), which hasnt gone away since i’ve been brushing. and his gums are red and inflamed The rest of his teeth, are PERFECT, and even whiter then mine. only the top 4 teeth are affected by this. Im willing to do anything to help him get better. Any suggestions on treatments?
