Omega-3 Improves Your Pet Health

Well, thats right. I’ve fallen into the Cavalier trap. I haven’t actually got one but I really really want one. But of course I’m not allowed one, got to do uni, then get a job, then I can get one. And I’ve still got loads of school years left…But I have fallen into the trap and I really want a Cav when I’m able to get one. Would they fit this lifestyle:
First time dog owner
Wants one that can go for lovely long walks but is alright missing one walk every now and then if I’m ill or something
Not aggressive
Easy to train
Very friendly and maybe good with other pets (I might get a cat or maybe another dog)
Good in the car
Will be left with my mum if I leave for long periods so will need to get use to two houses
Good with toilet training and what with me being the dog fanatic I am, lots of attention and cuddles and being spoilt ect ect
Also, I’ve taken many quizes on dog breeds suitable and best for me and it’s always given me the Cav but I overlook it because of the health problems

I would to add Cavalier King Charles Spaniel puppy to my family, i’ve made my research on that breed, but somehow i still can’t decide about the gender???
i wanted to get a bug, but many ppl told me not to get one, for their health problem, i have two himalayan cats who’s so used to dogs (my mom has a doberman & B Bulldog) so no worries, and i’m planning to get a puppy so he’ll get used to cats too,
what do you reckon??

i have a male cavalier king charles spaniel. hes about 5 years old now and recently i have been discovering pimple sized white/pinkish lumps on him. i found the first about a month ago on his back. a few days ago i found another lower on his back. tonight i found some between the pads on his feet. maybe two or three. should i be worried? i realize i should be taking him to a vet but its the holidays and i cant get him in right now. he also seems to be in moderate pain/discomfort. he will not jump up on the couch anymore and the last time he did, maybe two days ago, he cried out. serious answers only please. and for the record he has not had any health problems in these areas before. knock wood. please help!
