Can you own a dog on £1100 a month?

Depends on your other expenses. Sit down and make a realistic budget for your own expenses and the dog's. Stick to it for a while- say about six months. If you're able to adhere to the budget and have set aside every cent you had budgeted for the dogs care, then you likely can afford it. If you find yourself dipping into that money to fund other wants or needs, then you likely can't afford it. Also, presumably you don't want to live with your parents indefinitely. Consider what will happen to that budget when you move out of your parents' home and have rent, utilities, groceries, etc. to pay for as well.

look, on this forum if you're not rich and able to spend 24-7 with the dog, most will tell you you shouln't own a dog. Those of us with 2 connected brain cells will tell you that if you have a yard, I think y'all call it a garden, food water and shelter, why not enjoy a dog? A little put away for medical care is a good idea.

Yes. You need to be smart with your other bills. If you aren't paying rent this should be very manageable.

Don't know as this is a world wide site, so don't know what the cost of living is in your area. Have your parents given you permission to get a dog, it is after all their home, so they have the final say on whether they want a dog, in their home. Just as if you had to move out for what ever reason and had to find a pet friendly place, the landlord may also have breed/size restrictions, a pet fee, in addition to a security deposit may apply in addition to the monthly rent.

If you're a minor, you can't own or purchase property, dogs are property, nor can you sign any legal documents such as adoption papers, or give consent for vet care.

All other family members have to be in agreement in getting a dog, if they aren't the dog will suffer the most being in a home where it isn't wanted by everyone. Depending on what dog you're getting, don't forget to factor in the initial purchase price and/or an adoption fee. Dogs aren't a necessity they're a luxury.

Are you knowledgeable/experienced how to care, train and provide for a dogs needs, as no dog comes ready made to your whims, they require daily time/effort, patience, consistency, diligence, supervision, etc. Will you be able fit that into your schedule and continue working?

A dog shouldn't be left alone for more than 3-4 hours daily, without being taken outside and walked for elimination, once you've housebroken it, prior to being house broken, they may need to go for walk/elimination times every 1-2 hours, training doesn't happen in a matter of days, possibly weeks, most likely it could take six or more months.

In addition most dogs also require daily aerobic exercise, such as running/swimming, minimally 20-30 minutes, as well as daily mental stimulation, such as obedience training, 10-15 minutes, some dogs require 3-4 sessions daily of each, aerobic exercise and mental stimulation.

Dogs are 12-17 year commitment, regardless of any lifestyle/financial changes. Do you know where you will be at any time during those years?

Easily. My Social Security is just over $8,000.00 now. & over the last 50 yrs or so I have rescued large & extra large dogs & keep at least 5 at one time. I managed quite well even with Vet emergencies, & all my bills on less than what I am getting now. IF the dog is important to you, you will find a way.

It would make more sense to get pet insurance, rather than just storing up cash for emergencies.
