Hoping to find a vet or someone who can give me some advice on my animal/s!!

We have a year old lab/pit bull mix, we rescued her a handful of months ago. Just yesterday the whole right side of her face was completely swollen, her left cheek as well. We gave her 25mg of Benadryl and the swelling went down. She threw it up a few hours later and she threw up bile this morning. I just got home from work and she threw up her food and bits of twigs.

We recently rescued a 5 month old kitten and he’s also been vomiting. It was white and foamy at first and I thought nothing of it since he’s never had the issue before and there was hair in it. It’s now progressed to colored vomit and he has diarrhea. He seems sluggish but is eating and drinking normally.

Kita (dog) is eating Simply Nourish and Ronan (cat) is eating Rachel Ray: Nutrish.

Any advice or thoughts will help. I don’t want to go and spend hundreds at the vet for nothing!! TIA
